platform/x86: pmc_atom: Add Lex 2I385SW to critclk_systems DMI table

2020-04-02T13:28:23+00:00

commit 95b31e35239e5e1689e3d965d692a313c71bd8ab upstream.

The Lex 2I385SW board has two Intel I211 ethernet controllers. Without
this patch, only the first port is usable. The second port fails to
start with the following message:

    igb: probe of 0000:02:00.0 failed with error -2

platform/x86: intel_mid_powerbtn: Take a copy of ddata

2020-02-14T21:33:25+00:00

commit 5e0c94d3aeeecc68c573033f08d9678fecf253bd upstream.

The driver gets driver_data from memory that is marked as const (which
is probably put to read-only memory) and it then modifies it. This
likely causes some sort of fault to happen.

Fix this by taking a copy of the structure.

platform/x86: intel_scu_ipc: Fix interrupt support

2020-02-11T12:33:57+00:00

commit e48b72a568bbd641c91dad354138d3c17d03ee6f upstream.

Currently the driver has disabled interrupt support for Tangier but
actually interrupt works just fine if the command is not written twice
in a row. Also we need to ack the interrupt in the handler.

platform/x86: GPD pocket fan: Allow somewhat lower/higher temperature limits

2020-02-05T14:43:44+00:00

[ Upstream commit 1f27dbd8265dbb379926c8f6a4453fe7fe26d7a3 ]

Allow the user to configure the fan to turn on / speed-up at lower
thresholds then before (20 degrees Celcius as minimum instead of 40) and
likewise also allow the user to delay the fan speeding-up till the
temperature hits 90 degrees Celcius (was 70).

platform/x86: dell-laptop: disable kbd backlight on Inspiron 10xx

2020-02-01T09:37:09+00:00

[ Upstream commit 10b65e2915b2fcc606d173e98a972850101fb4c4 ]

This patch adds a quirk disabling keyboard backlight support for the
Dell Inspiron 1012 and 1018.

Those models wrongly report supporting keyboard backlight control
features (through SMBIOS tokens) even though they're not equipped with
a backlit keyboard. This led to broken controls being exposed
through sysfs by this driver which froze the system when used.

platform/x86: alienware-wmi: printing the wrong error code

The "out_data" variable is uninitialized at the point.  Originally, this
used to print "status" instead and that seems like the correct thing to

platform/x86: alienware-wmi: fix kfree on potentially uninitialized pointer

2020-01-27T13:50:39+00:00

[ Upstream commit 98e2630284ab741804bd0713e932e725466f2f84 ]

Currently the kfree of output.pointer can be potentially freeing
an uninitalized pointer in the case where out_data is NULL. Fix this
by reworking the case where out_data is not-null to perform the
ACPI status check and also the kfree of outpoint.pointer in one block
and hence ensuring the pointer is only freed when it has been used.

Also replace the if (ptr != NULL) idiom with just if (ptr).

platform/x86: wmi: fix potential null pointer dereference

[ Upstream commit c355ec651a8941864549f2586f969d0eb7bf499a ]

In the function wmi_dev_match() the variable id is dereferenced without
first performing a NULL check. The variable can for example be NULL if
a WMI driver is registered without specifying the id_table field in
struct wmi_driver.

Add a NULL check and return that the driver can't handle the device if
the variable is NULL.

platform/x86: GPD pocket fan: Use default values when wrong modparams are given

2020-01-17T18:47:04+00:00

commit 6ae01050e49f0080ae30575d9b45a6d4a3d7ee23 upstream.

Use our default values when wrong module-parameters are given, instead of
refusing to load. Refusing to load leaves the fan at the BIOS default
setting, which is "Off". The CPU's thermal throttling should protect the
system from damage, but not-loading is really not the best fallback in this
case.

This commit fixes this by re-setting module-parameter values to their
defaults if they are out of range, instead of failing the probe with
-EINVAL.
