platform/x86: thinkpad_acpi: Fix WWAN device disabled issue after S3 deep

2021-11-16T09:56:53+00:00

When WWAN device wake from S3 deep, under thinkpad platform,
WWAN would be disabled. This disable status could be checked
by command 'nmcli r wwan' or 'rfkill list'.

Issue analysis as below:
  When host resume from S3 deep, thinkpad_acpi driver would
call hotkey_resume() function. Finnaly, it will use
wan_get_status to check the current status of WWAN device.
During this resume progress, wan_get_status would always
return off even WWAN boot up completely.
  In patch V2, Hans said 'sw_state should be unchanged
after a suspend/resume. It's better to drop the
tpacpi_rfk_update_swstate call all together from the
resume path'.
  And it's confimed by Lenovo that GWAN is no longer
 available from WHL generation because the design does not
 match with current pin control.

platform/x86: think-lmi: Abort probe on analyze failure

2021-11-16T09:56:53+00:00

A Lenovo ThinkStation S20 (4157CTO BIOS 60KT41AUS) fails to boot on
recent kernels including the think-lmi driver, due to the fact that
errors returned by the tlmi_analyze() function are ignored by
tlmi_probe(), where  tlmi_sysfs_init() is called unconditionally.
This results in making use of an array of already freed, non-null
pointers and other uninitialized globals, causing all sorts of nasty
kobject and memory faults.

Make use of the analyze function return value, free a couple leaked
allocations, and remove the settings_count field, which is incremented
but never consumed.

platform/x86: dell-wmi-descriptor: disable by default

2021-11-16T09:56:53+00:00

dell-wmi-descriptor only provides symbols to other drivers.
These drivers already select dell-wmi-descriptor when needed.

This fixes an issue where dell-wmi-descriptor is compiled as a module
with localyesconfig on a non-Dell machine.

platform/mellanox: mlxreg-lc: fix error code in mlxreg_lc_create_static_devices()

2021-11-16T09:19:46+00:00

This code should be using PTR_ERR() instead of IS_ERR().  And because
it's using the wrong "dev->client" pointer, the IS_ERR() check will be
false, meaning the function returns success.

  Included are:

   - habanana labs driver updates, including dma_buf usage, reviewed and
     acked by the dma_buf maintainers

   - iio driver update (going through this tree not staging as they
     really do not belong going through that tree anymore)

     hwmon maintainer

   - xillybus driver updates

   - binder driver updates

   - extcon driver updates

   - dma_buf module namespaces added (will cause a build error in arm64
     for allmodconfig, but that change is on its way through the drm
