8c2eb7b646 platform/mellanox: mlxreg-hotplug: Add devm_free_irq call to remove flow
Add devm_free_irq() call to mlxreg-hotplug remove() for clean release
of devices irq resource. Fix debugobjects warning triggered by rmmod
It prevents of use-after-free memory, related to
mlxreg_hotplug_work_handler.

Issue has been reported as debugobjects warning triggered by
'rmmod mlxtreg-hotplug' flow, while running kernel with
CONFIG_DEBUG_OBJECTS* options.

160da20b25 platform/x86: mlx-platform: Fix parent device in i2c-mux-reg device registration
Fix the issue found while running kernel with the option
CONFIG_DEBUG_TEST_DRIVER_REMOVE.
Driver 'mlx-platform' registers 'i2c_mlxcpld' device and then registers
few underlying 'i2c-mux-reg' devices:
	priv->pdev_i2c = platform_device_register_simple("i2c_mlxcpld", nr,
							 NULL, 0);
	...
	for (i = 0; i < ARRAY_SIZE(mlxplat_mux_data); i++) {
		priv->pdev_mux[i] = platform_device_register_resndata(
						&mlxplat_dev->dev,
						"i2c-mux-reg", i, NULL,
						0, &mlxplat_mux_data[i],
						sizeof(mlxplat_mux_data[i]));

But actual parent of "i2c-mux-reg" device is priv->pdev_i2c->dev and
not mlxplat_dev->dev.
Patch fixes parent device parameter in a call to
platform_device_register_resndata() for "i2c-mux-reg".

It solves the race during initialization flow while 'i2c_mlxcpld.1' is
removing after probe, while 'i2c-mux-reg.0' is still in probing flow:
'i2c_mlxcpld.1'	flow:	probe -> remove -> probe.
'i2c-mux-reg.0'	flow:		  probe -> ...

cb1921b17a platform/x86: intel-vbtn: Report switch events when event wakes device
When a switch event, such as tablet mode/laptop mode or docked/undocked,
wakes a device make sure that the value of the swich is reported.
Without when a device is put in tablet mode from laptop mode when it is
suspended or vice versa the device will wake up but mode will be
incorrect.

Tested by suspending a device in laptop mode and putting it in tablet
mode, the device resumes and is in tablet mode. When suspending the
device in tablet mode and putting it in laptop mode the device resumes
and is in laptop mode.

401fee8195 platform/x86: asus-wmi: Only Tell EC the OS will handle display hotkeys from asus_nb_wmi
Commit 78f3ac76d9 ("platform/x86: asus-wmi: Tell the EC the OS will
handle the display off hotkey") causes the backlight to be permanently off
on various EeePC laptop models using the eeepc-wmi driver (Asus EeePC
1015BX, Asus EeePC 1025C).

The asus_wmi_set_devstate(ASUS_WMI_DEVID_BACKLIGHT, 2, NULL) call added
by that commit is made conditional in this commit and only enabled in
the quirk_entry structs in the asus-nb-wmi driver fixing the broken
display / backlight on various EeePC laptop models.

Pule more SPDX updates from Greg KH:
 "Here is another set of reviewed patches that adds SPDX tags to
  different kernel files, based on a set of rules that are being used to
  parse the comments to try to determine that the license of the file is
  "GPL-2.0-or-later".

  Only the "obvious" versions of these matches are included here, a
  number of "non-obvious" variants of text have been found but those
  have been postponed for later review and analysis.

  These patches have been out for review on the linux-spdx@vger mailing
  list, and while they were created by automatic tools, they were
  hand-verified by a bunch of different people, all whom names are on
  the patches are reviewers"
