Merge tag 'leds-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds
Pull LED updates from Pavel Machek:
"Small cleanups/fixes mostly thanks to Marek, nothing major made it in
this time"
* tag 'leds-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds:
leds: turris-omnia: check for LED_COLOR_ID_RGB instead LED_COLOR_ID_MULTI
leds: turris-omnia: fix checkpatch warning
leds: turris-omnia: wrap to 80 columns
leds: turris-omnia: use constants instead of macros for color command
dt-bindings: leds: Convert pwm to yaml
leds: lp50xx: Fix an error handling path in 'lp50xx_probe_dt()'
leds: netxbig: add missing put_device() call in netxbig_leds_get_of_pdata()
Documentation: leds: remove invalidated information
