Merge tag 'leds-next-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds
Pull LED updates from Lee Jones:
"Core Framework:
- Introduce ExpressWire library
New Drivers:
- Add support for ON Semiconductor NCP5623 RGB LED Driver
New Device Support:
- Add support for PM660L to Qualcomm's LPG driver
New Functionality:
- Dynamically load modules required for the default-trigger
- Add some support for suspend and resume
- Allow LEDs to remain lit during suspend
Fix-ups:
- Device Tree binding adaptions/conversions/creation
- Fix include lists; alphabetise, remove unused, explicitly add used
- Add new led_match_default_trigger to avoid duplication
- Add module alias' to aid auto-loading
- Default to hw_control if no others are specified
- De-bloat the supported link speed attribute lists
- Remove superfluous code and simplify overall
- Constify some variables
Bug Fixes:
- Prevent kernel panic when renaming the net interface
- Fix Kconfig related build errors
- Ensure mutexes are unlocked prior to destroying them
- Provide clean-up between state changes to avoid invalid state
- Fix some broken kernel-doc headers"
