kernel faults when a hotkey is sent or at kernel shutdown.

loongson_laptop_turn_{on,off}_backlight() are designed for controlling
the power of the backlight, but they aren't really used in the driver
previously.

Unify these two functions since they only differ in arguments passed to
ACPI method, and wire up loongson_laptop_backlight_update() to update
the power state of the backlight as well. Tested on the TongFang L860-T2
Loongson-3A5000 laptop.

Previously during driver probe, 1 is unconditionally taken as current
brightness value and set to props.brightness, which will be considered
as the brightness before suspend and restored to EC on resume. Since a
brightness value of 1 almost never matches EC's state on coldboot (my
laptop's EC defaults to 80), this causes surprising changes of screen
brightness on the first time of resume after coldboot.

Let's get brightness from EC and take it as the current brightness on
probe of the laptop driver to avoid the surprising behavior. Tested on
TongFang L860-T2 Loongson-3A5000 laptop.

Pull drm updates from Dave Airlie:
 "As part of building up nova-core/nova-drm pieces we've brought in some
  rust abstractions through this tree, aux bus being the main one, with
  devres changes also in the driver-core tree. Along with the drm core
  abstractions and enough nova-core/nova-drm to use them. This is still
  all stub work under construction, to build the nova driver upstream.

  The other big NVIDIA related one is nouveau adds support for
  Hopper/Blackwell GPUs, this required a new GSP firmware update to
  570.144, and a bunch of rework in order to support multiple fw
  interfaces.

Pull gpio updates from Bartosz Golaszewski:
 "We have three new drivers, some refactoring in the GPIO core, lots of
  various changes across many drivers, new configfs interface for the
  virtual gpio-aggregator module and DT-bindings updates.

  The treewide conversion of GPIO drivers to using the new value setter
  callbacks is ongoing with another round of GPIO drivers updated. You
  will also see these commits coming in from other subsystems as with
  the relevant changes merged into mainline last cycle, I've started
  converting GPIO providers located elsewhere than drivers/gpio/.

  GPIO core:
   - use more lock guards where applicable
   - refactor GPIO ACPI code and shrink it in the process by 8%
   - move GPIO ACPI quirks into a separate file
   - remove unneeded #ifdef
   - convert GPIO devres helpers to using devm_add_action() where
     applicable which shrinks and simplifies the code
   - refactor GPIO descriptor validation in GPIO consumer interfaces
   - don't allow setting values on input lines in the GPIO core which
     will take off the burden from GPIO drivers of checking this down
     the line
   - provide gpiod_is_equal() as a way of safely comparing two GPIO
     descriptors (the only current user is in regulator core)

  New drivers:
   - add the GPIO module for the max77759 multifunction device
   - add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
   - add the GPIO driver for the Spacemit K1 SoC

  Driver improvements:
   - convert more drivers to using the new GPIO line value setter
     callbacks
   - convert more drivers to making the irq_chip immutable as is
     recommended by the interrupt subsystem
   - extend build testing coverage by enabling more modules to be built
     with COMPILE_TEST=y
   - extend the gpio-aggregator module with a configfs interface that
     makes the setup easier for user-space than the existing
     driver-level sysfs attributes and also adds more advanced
     configuration features (such as referring to aggregated lines by
     their original names or modifying their names as exposed by the
     aggregated chip)
   - add a missing mutex_destroy() in gpio-imx-scu
   - add an OF polarity quirk for s5m8767
   - allow building gpio-vf610 as a loadable module
   - make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
     interface disabled (another small step towards getting rid of the
     global GPIO numberspace)
   - add support for level-triggered interrupts to gpio-pca953x
   - don't double-check the ngpios property in gpio-ds4520 as GPIO core
     already does it
   - don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
     already does it
   - remove unused callbacks from gpio-max3191x

  DT bindings:
   - add device-tree bindings for max77759, spacemit,k1 and blzp1600
     (new drivers added this cycle)
   - document more properties for gpio-vf610 and gpio-tegra186
   - document a new pca95xx variant
   - fix style of examples in several GPIO DT-binding documents

   - TODO list updates"
