ACPI video_detect.c
acpi_video_set_dmi_backlight_type() is troublesome because it may end up
getting called after other backlight drivers have already called
acpi_video_get_backlight_type() resulting in the other drivers
already being registered even though they should not.
Move all the acpi_backlight=[vendor|native] quirks from samsung-laptop to
drivers/acpi/video_detect.c .
Note the X360 -> acpi_backlight=native quirk is not moved because that
already was present in drivers/acpi/video_detect.c .

Remove the asus-wmi quirk_entry.wmi_backlight_power quirk-flag, which

Note no entries are dropped from the dmi_system_id table in asus-nb-wmi.c.
This is because the entries using the removed wmi_backlight_power flag
also use other model specific quirks from the asus-wmi quirk_entry struct.
So the quirk_asus_x55u struct and the entries pointing to it cannot be
dropped.

Remove this check from the asus-wmi backlight handling:
/* Some Asus desktop boards export an acpi-video backlight interface,
stop this from showing up */
chassis_type = dmi_get_system_info(DMI_CHASSIS_TYPE);
if (chassis_type && !strcmp(chassis_type, "3"))
acpi_video_set_dmi_backlight_type(acpi_backlight_vendor);
This acpi_video_set_dmi_backlight_type(acpi_backlight_vendor) call must be
removed because other changes in this series change the native backlight
drivers to no longer unconditionally register their backlight. Instead
these drivers now do this check:
if (acpi_video_get_backlight_type(false) != acpi_backlight_native)
return 0; /* bail */
So leaving this in place can break things on laptops with a broken
DMI chassis-type, which would have GPU native brightness control before
the addition of the acpi_video_get_backlight_type() != native check.
Removing this should be ok now, since the ACPI video code has improved
heuristics for this itself now (which includes a chassis-type check).

Move the backlight DMI quirks to acpi/video_detect.c, so that
the driver no longer needs to call acpi_video_set_dmi_backlight_type().
acpi_video_set_dmi_backlight_type() is troublesome because it may end up
getting called after other backlight drivers have already called
acpi_video_get_backlight_type() resulting in the other drivers
already being registered even though they should not.
Note that even though the DMI quirk table name was video_vendor_dmi_table,
5/6 quirks were actually quirks to use the GPU native backlight.
These 5 quirks also had a callback in their dmi_system_id entry which
disabled the acer-wmi vendor driver; and any DMI match resulted in:
acpi_video_set_dmi_backlight_type(acpi_backlight_vendor);
which disabled the acpi_video driver, so only the native driver was left.
The new entries for these 5/6 devices correctly marks these as needing
the native backlight driver.
Also note that other changes in this series change the native backlight
drivers to no longer unconditionally register their backlight. Instead
these drivers now do this check:
if (acpi_video_get_backlight_type(false) != acpi_backlight_native)
return 0; /* bail */
which without this patch would have broken these 5/6 "special" quirks.
Since I had to look at all the commits adding the quirks anyways, to make
sure that I understood the code correctly, I've also added links to
the various original bugzillas for these quirks to the new entries.

acpi_video_set_dmi_backlight_type() is troublesome because it may end up
getting called after other backlight drivers have already called
acpi_video_get_backlight_type() resulting in the other drivers
already being registered even though they should not.
In case of the acpi_video backlight, acpi_video_set_dmi_backlight_type()
actually calls acpi_video_unregister_backlight() since that is often
probed earlier, leading to userspace seeing the acpi_video0 class
device being briefly available, leading to races in userspace where
udev probe-rules try to access the device and it is already gone.
In case of toshiba_acpi there are no DMI quirks to move to
acpi/video_detect.c, but it also (ab)uses it for transflective
displays. Adding transflective display support to video_detect.c would
be quite involved. But luckily there are only 2 known models with
a transflective display, so we can just add DMI quirks for those.

Now that acpi_video_get_backlight_type() has apple-gmux detection (using
apple_gmux_present()), it is no longer necessary for the apple-gmux code
to manually remove possibly conflicting drivers.
So remove the handling for this from the apple-gmux driver.

Add an acpi_video_get_backlight_type() == acpi_backlight_nvidia_wmi_ec
check. This will make nvidia-wmi-ec-backlight properly honor the user
selecting a different backlight driver through the acpi_backlight=...
kernel commandline option.
Since the auto-detect code check for nvidia-wmi-ec-backlight in
drivers/acpi/video_detect.c already checks that the WMI advertised
brightness-source is the embedded controller, this new check makes it
unnecessary for nvidia_wmi_ec_backlight_probe() to check this itself.

This reverts commit a10fba0377145fccefea4dc4dd5915b7ed87e546: the
proposed API isn't supported on all transports but no
effort was made to address this.
It might not be hard to fix if we want to: maybe just
rename size to size_hint and make sure legacy
transports ignore the hint.
But it's not sure what the benefit is in any case, so
let's drop it.

find_vqs() adds a new parameter sizes to specify the size of each vq
vring.
NULL as sizes means that all queues in find_vqs() use the maximum size.
A value in the array is 0, which means that the corresponding queue uses
the maximum size.
In the split scenario, the meaning of size is the largest size, because
it may be limited by memory, the virtio core will try a smaller size.
And the size is power of 2.

The call to:
size = simple_write_to_buffer(cmdbuf, sizeof(cmdbuf), ppos, buf, size);
will succeed if at least one byte is written to the "cmdbuf" buffer.
The "*ppos" value controls which byte is written. Another problem is
that this code does not check for errors so it's possible for the entire
buffer to be uninitialized.
Inintialize the struct to zero to prevent reading uninitialized stack
data.
Debugfs is normally only writable by root so the impact of this bug is
very minimal.

Fix error flow:
- Clean-up client object in case of probing failure.
- Prevent running remove routine in case of probing failure.
Probing and removing are invoked by hotplug events raised upon line
card insertion and removing. If probing procedure failed all data is
cleared and there is nothing to do in remove routine.

DMI table
The critclk_systems[] DMI match table already contains 2 Lex BayTrail
boards and patches were just submitted to add 3 more entries for the
following models: 3I380NX, 3I380A, 3I380CW.
Looking at: https://www.lex.com.tw/products/embedded-ipc-board/
we can see that Lex BayTrail makes many embedded boards with
multiple ethernet boards and none of their products are battery
powered so we don't need to worry (too much) about power consumption
when suspended.
Add a new DMI match which simply matches all Lex BayTrail boards and drop
the 2 existing board specific quirks.

drivers/platform/chrome/cros_kbd_led_backlight.c got a new build warning
when using the randconfig in [1]:
>>> warning: unused variable 'keyboard_led_drvdata_ec_pwm'
The warning happens when CONFIG_CROS_EC is set but CONFIG_OF is not set.
Reproduce:
- mkdir build_dir
- wget [1] -O build_dir/.config
- COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross W=1 \
O=build_dir ARCH=s390 SHELL=/bin/bash drivers/platform/chrome/
Fix the warning by using __maybe_unused. Also use IS_ENABLED() because
CROS_EC is a tristate.
