Merge tag 'leds-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds
Pull LED updates from Pavel Machek: "Besides the usual fixes and new drivers, we are changing CLASS_FLASH to return success to make it easier to work with V4L2 stuff disabled, and we are getting rid of enum that should have been plain integer long time ago. I'm slightly nervous about potential warnings, but it needed to be fixed at some point" * tag 'leds-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds: leds: lp50xx: Get rid of redundant explicit casting leds: lp50xx: Update headers block to reflect reality leds: lp50xx: Get rid of redundant check in lp50xx_enable_disable() leds: lp50xx: Reduce level of dereferences leds: lp50xx: Switch to new style i2c-driver probe function leds: lp50xx: Don't spam logs when probe is deferred leds: apu: extend support for PC Engines APU1 with newer firmware leds: flash: Fix multicolor no-ops registration by return 0 leds: flash: Add flash registration with undefined CONFIG_LEDS_CLASS_FLASH leds: lgm: Add LED controller driver for LGM SoC dt-bindings: leds: Add bindings for Intel LGM SoC leds: led-core: Get rid of enum led_brightness leds: gpio: Set max brightness to 1 leds: lm3533: Switch to using the new API kobj_to_dev() leds: ss4200: simplify the return expression of register_nasgpio_led() leds: Use DEVICE_ATTR_{RW, RO, WO} macros
