[ Upstream commit 94be878c882d8d784ff44c639bf55f3b029f85af ]
The length of hw->settings->odr_table is 2 and ref_sensor->id is an enum
variable whose value is between 0 and 5.
However, the value ST_LSM6DSX_ID_MAX (i.e. 5) is not caught properly in
switch (sensor->id) {
If ref_sensor->id is ST_LSM6DSX_ID_MAX, an array overflow will ocurrs in
function st_lsm6dsx_check_odr():
odr_table = &sensor->hw->settings->odr_table[sensor->id];
and in function st_lsm6dsx_set_odr():
reg = &hw->settings->odr_table[ref_sensor->id].reg;
To avoid this array overflow, handle ST_LSM6DSX_ID_GYRO explicitly and
return -EINVAL for the default case.
The enum value ST_LSM6DSX_ID_MAX is only present as an easy way to check
the limit and as such is never used, however this is not locally obvious.

[ Upstream commit b600bd7eb333554518b4dd36b882b2ae58a5149e ]
With commit ecb010d441088 ("iio: imu: adis: Refactor adis_initial_startup")
we are doing a HW or SW reset to the device which means that we'll get
the default state of the data ready pin (which is enabled). Hence there's
no point in disabling the IRQ in the init function. Moreover, this
function is intended to initialize internal data structures and not
really do anything on the device.
As a result of this, some devices were left with the data ready pin enabled
after probe which was not the desired behavior. Thus, we move the call to
'adis_enable_irq()' to the initial startup function where it makes more
sense for it to be.
Note that for devices that cannot mask/unmask the pin, it makes no sense
to call the function at this point since the IRQ should not have been
yet requested. This will be improved in a follow up change.

[ Upstream commit 9f0b3e0cc0c88618aa9e5cecef747b1337ae0a5d ]
Up until commit ea7e586bdd331 ("iio: st_sensors: move regulator retrieveal
to core") only the ST pressure driver seems to have had any regulator
disable. After that commit, the regulator handling was moved into the
common st_sensors logic.
In all instances of this regulator handling, the regulators were disabled
before unregistering the IIO device.
This can cause issues where the device would be powered down and still be
available to userspace, allowing it to send invalid/garbage data.
This change moves the st_sensors_power_disable() after the common probe
functions. These common probe functions also handle unregistering the IIO
device.

commit 26df977a909f818b7d346b3990735513e7e0bf93 upstream.
The bindings file for this driver is defining the property as 'reg' but
the driver was reading it with the 'num' name. The bindings actually had
the 'num' property when added in
commit ea52c21268e6 ("dt-bindings: iio: dac: Add docs for AD5770R DAC")
and then changed it to 'reg' in
commit 2cf3818f18b2 ("dt-bindings: iio: dac: AD5570R fix bindings errors").
However, both these commits landed in v5.7 so the assumption is
that either 'num' is not being used or if it is, the validations were not
done.
Anyways, if someone comes back yelling about this, we might just support
both of the properties in the future. Not ideal, but that's life...

commit 558df982d4ead9cac628153d0d7b60feae05ddc8 upstream.
On success i2c_master_send() returns the number of bytes written. The
call from iio_write_channel_info(), however, expects the return value to

This bug causes incorrect consumption of the sysfs buffer in

out_voltage0_raw, the ad5446 write handler is called multiple times

[ Upstream commit 97683c851f9cdbd3ea55697cbe2dcb6af4287bbd ]
The naming of the regulator is problematic. VCC is usually a supply
voltage whereas these devices have a separate VREF pin.
Secondly, the regulator core might have provided a stub regulator if
a real regulator wasn't provided. That would in turn have failed to
provide a voltage when queried. So reality was that there was no way
to use the internal reference.
In order to avoid breaking any dts out in the wild, make sure to fallback
to the original vcc naming if vref is not available.

commit b76d26d69ecc97ebb24aaf40427a13c808a4f488 upstream.
There is no reason to assume that the IRQ rising edge (indicating that
the device start up phase is done) will happen after we request the IRQ.
If the device is already up by the time we request it, the call to
'wait_for_completion_timeout()' will timeout and we will fail the device
probe even though there's nothing wrong.
Fix it by just polling the status register until we get the indication that
the device is up and running. As a side effect of this fix, requesting the
IRQ is also moved to after the setup function.

The ADS7950 requires that CS is deasserted after each SPI word. Before
commit e2540da86ef8 ("iio: adc: ti-ads7950: use SPI_CS_WORD to reduce

where each but the last one had .cs_change set to enforce a CS toggle.
This was wrongly translated into a message with a single transfer and
.cs_change set which results in a CS toggle after each word but the
last which corrupts the first adc conversion of all readouts after the
first readout.

it is not clear why that would be necessary.

iio_push_to_buffers_with_timestamp()
[ Upstream commit 92babc9938ebbf4050f2fba774836f7edc16a570 ]
Add __aligned(8) to ensure the buffer passed to
iio_push_to_buffers_with_timestamp() is suitable for the naturally
aligned timestamp that will be inserted.
Here an explicit structure is not used, because the holes would
necessitate the addition of an explict memset(), to avoid a kernel
data leak, making for a less minimal fix.
