commit f16b7d2a5e810fcf4b15d096246d0d445da9cc88 upstream.
Following the introduction of the generic ECC engine infrastructure, it
was necessary to reorganize the code and move the ECC configuration in
the ->attach_chip() hook. Failing to do that properly lead to a first
series of fixes supposed to stabilize the situation. Unfortunately, this
only fixed the use of software ECC engines, preventing any other kind of
engine to be used, including on-die ones.
It is now time to (finally) fix the situation by ensuring that we still
provide a default (eg. software ECC) but will still support different
ECC engines such as on-die ECC engines if properly described in the
device tree.
There are no changes needed on the core side in order to do this, but we
just need to leverage the logic there which allows:
1- a subsystem default (set to Host engines in the raw NAND world)
2- a driver specific default (here set to software ECC engines)
3- any type of engine requested by the user (ie. described in the DT)
As the raw NAND subsystem has not yet been fully converted to the ECC
engine infrastructure, in order to provide a default ECC engine for this
driver we need to set chip->ecc.engine_type *before* calling
nand_scan(). During the initialization step, the core will consider this
entry as the default engine for this driver. This value may of course
be overloaded by the user if the usual DT properties are provided.

commit ad9a14517263a16af040598c7920c09ca9670a31 upstream.
Since commit 48720ba56891 ("virtio/s390: use DMA memory for ccw I/O and
classic notifiers") we were supposed to make sure that
virtio_ccw_release_dev() completes before the ccw device and the
attached dma pool are torn down, but unfortunately we did not. Before
that commit it used to be OK to delay cleaning up the memory allocated
by virtio-ccw indefinitely (which isn't really intuitive for guys used
to destruction happens in reverse construction order), but now we
trigger a BUG_ON if the genpool is destroyed before all memory allocated
from it is deallocated. Which brings down the guest. We can observe this
problem, when unregister_virtio_device() does not give up the last
reference to the virtio_device (e.g. because a virtio-scsi attached scsi
disk got removed without previously unmounting its previously mounted
partition).
To make sure that the genpool is only destroyed after all the necessary
freeing is done let us take a reference on the ccw device on each
ccw_device_dma_zalloc() and give it up on each ccw_device_dma_free().
Actually there are multiple approaches to fixing the problem at hand
that can work. The upside of this one is that it is the safest one while
remaining simple. We don't crash the guest even if the driver does not
pair allocations and frees. The downside is the reference counting
overhead, that the reference counting for ccw devices becomes more
complex, in a sense that we need to pair the calls to the aforementioned
functions for it to be correct, and that if we happen to leak, we leak
more than necessary (the whole ccw device instead of just the genpool).
Some alternatives to this approach are taking a reference in
virtio_ccw_online() and giving it up in virtio_ccw_release_dev() or
making sure virtio_ccw_release_dev() completes its work before
virtio_ccw_remove() returns. The downside of these approaches is that
these are less safe against programming errors.

commit 3826350e6dd435e244eb6e47abad5a47c169ebc2 upstream.
When a queue is switched to soft offline during heavy load and later
switched to soft online again and now used, it may be that the caller
is blocked forever in the ioctl call.
The failure occurs because there is a pending reply after the queue(s)
have been switched to offline. This orphaned reply is received when
the queue is switched to online and is accidentally counted for the
outstanding replies. So when there was a valid outstanding reply and
this orphaned reply is received it counts as the outstanding one thus
dropping the outstanding counter to 0. Voila, with this counter the
receive function is not called any more and the real outstanding reply
is never received (until another request comes in...) and the ioctl
blocks.
The fix is simple. However, instead of readjusting the counter when an
orphaned reply is detected, I check the queue status for not empty and
compare this to the outstanding counter. So if the queue is not empty
then the counter must not drop to 0 but at least have a value of 1.

commit 33a5471f8da976bf271a1ebbd6b9d163cb0cb6aa upstream.
The note in c2adda27d202f ("video: backlight: Add of_find_backlight helper
in backlight.c") says that gpio-backlight uses brightness as power state.
This has been fixed since in ec665b756e6f7 ("backlight: gpio-backlight:
Correct initial power state handling") and other backlight drivers do not
require this workaround. Drop the workaround.
This fixes the case where e.g. pwm-backlight can perfectly well be set to
brightness 0 on boot in DT, which without this patch leads to the display
brightness to be max instead of off.

commit 313c84b5ae4104e48c661d5d706f9f4c425fd50f upstream.
This patch extends the DLN2 driver; adding cell for adc_dln2 module.
The original patch[1] fell through the cracks when the driver was added
so ADC has never actually been usable. That patch did not have ACPI
support which was added in v5.9, so the oldest supported version this
current patch can be backported to is 5.10.

commit 69ea463021be0d159ab30f96195fb0dd18ee2272 upstream.
When using "devm_request_threaded_irq(,,,,IRQF_ONESHOT,,)" in a driver,
only the first interrupt is handled, and following interrupts are never
delivered (initially reported in [1]).
That's because the RISC-V PLIC cannot EOI masked interrupts, as explained
in the description of Interrupt Completion in the PLIC spec [2]:
<quote>
The PLIC signals it has completed executing an interrupt handler by
writing the interrupt ID it received from the claim to the claim/complete
register. The PLIC does not check whether the completion ID is the same
as the last claim ID for that target. If the completion ID does not match
an interrupt source that *is currently enabled* for the target, the
completion is silently ignored.
</quote>
Re-enable the interrupt before completion if it has been masked during
the handling, and remask it afterwards.

snprintf() returns the number of bytes it would have printed if there
were space. But it does not count the NUL terminator. So that means
that if "count == copied" then this has already overflowed by one
character.
This bug likely isn't super harmful in real life.

Put new_slave in bond_sysfs_slave_add() will cause use-after-free problems
when new_slave is accessed in the subsequent error handling process. Since
new_slave will be put in the subsequent error handling process, remove the
unnecessary put to fix it.
In addition, when sysfs_create_file() fails, if some files have been crea-
ted successfully, we need to call sysfs_remove_file() to remove them.
Since there are sysfs_create_files() & sysfs_remove_files() can be used,
use these two functions instead.

As reported by Zhang there's a small issue if in forced mode the duplex
mode changes with the link staying up [0]. In this case the MAC isn't
notified about the change.
The proposed patch relies on the phylib state machine and ignores the
fact that there are drivers that uses phylib but not the phylib state
machine. So let's don't change the behavior for such drivers and fix
it w/o re-adding state PHY_FORCING for the case that phylib state
machine is used.

[ Upstream commit 009a789443fe4c8e6b1ecb7c16b4865c026184cd ]
The handling of PMIC register reads through writing 0 to address 4
of the OpRegion is wrong. Instead of returning the read value
through the value64, which is a no-op for function == ACPI_WRITE calls,
store the value and then on a subsequent function == ACPI_READ with
address == 3 (the address for the value field of the OpRegion)
return the stored value.
This has been tested on a Xiaomi Mi Pad 2 and makes the ACPI battery dev
there mostly functional (unfortunately there are still other issues).
Here are the SET() / GET() functions of the PMIC ACPI device,
which use this OpRegion, which clearly show the new behavior to
be correct:
OperationRegion (REGS, 0x8F, Zero, 0x50)
Field (REGS, ByteAcc, NoLock, Preserve)
{
CLNT, 8,
SA, 8,
OFF, 8,
VAL, 8,
RWM, 8
}

{
If ((AVBE == One))
{
CLNT = Arg0
SA = Arg1
OFF = Arg2
RWM = Zero
If ((AVBG == One))
{

}
}

}

[ Upstream commit b385cca47363316c6d9a74ae9db407bbc281f815 ]
When a VF is removed and/or reset its Tx queues need to be
stopped from the PF. This is done by calling the ice_dis_vf_qs()
function, which calls ice_vsi_stop_lan_tx_rings(). Currently
ice_dis_vf_qs() is protected by the VF state bit ICE_VF_STATE_QS_ENA.
Unfortunately, this is causing the Tx queues to not be disabled in some
cases and when the VF tries to re-enable/reconfigure its Tx queues over
virtchnl the op is failing. This is because a VF can be reset and/or
removed before the ICE_VF_STATE_QS_ENA bit is set, but the Tx queues
were already configured via ice_vsi_cfg_single_txq() in the
VIRTCHNL_OP_CONFIG_VSI_QUEUES op. However, the ICE_VF_STATE_QS_ENA bit
is set on a successful VIRTCHNL_OP_ENABLE_QUEUES, which will always
happen after the VIRTCHNL_OP_CONFIG_VSI_QUEUES op.
This was causing the following error message when loading the ice
driver, creating VFs, and modifying VF trust in an endless loop:
[35274.192484] ice 0000:88:00.0: Failed to set LAN Tx queue context, error: ICE_ERR_PARAM
[35274.193074] ice 0000:88:00.0: VF 0 failed opcode 6, retval: -5
[35274.193640] iavf 0000:88:01.0: PF returned error -5 (IAVF_ERR_PARAM) to our request 6
Fix this by always calling ice_dis_vf_qs() and silencing the error
message in ice_vsi_stop_tx_ring() since the calling code ignores the
return anyway. Also, all other places that call ice_vsi_stop_tx_ring()
catch the error, so this doesn't affect those flows since there was no
change to the values the function returns.
Other solutions were considered (i.e. tracking which VF queues had been
"started/configured" in VIRTCHNL_OP_CONFIG_VSI_QUEUES, but it seemed
more complicated than it was worth. This solution also brings in the
chance for other unexpected conditions due to invalid state bit checks.
So, the proposed solution seemed like the best option since there is no
harm in failing to stop Tx queues that were never started.
This issue can be seen using the following commands:
for i in {0..50}; do
rmmod ice
modprobe ice
sleep 1
echo 1 > /sys/class/net/ens785f0/device/sriov_numvfs
echo 1 > /sys/class/net/ens785f1/device/sriov_numvfs

[ Upstream commit bb2ca6b3f09ac20e8357d257d0557ab5ddf6adcd ]
For RSCN of type "Area, Domain, or Fabric", which indicate a portion or
entire fabric was disturbed, current driver does not set the scan_need flag
to indicate a session was affected by the disturbance. This in turn can
lead to I/O timeout and delay of relogin. Hence initiate relogin in the
event of fabric disturbance.
