Merge tag 'leds_for_4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED updates from Jacek Anaszewski:
"LED class drivers improvements:
leds-pca955x:
- add Device Tree support and bindings
- use devm_led_classdev_register()
- add GPIO support
- prevent crippled LED class device name
- check for I2C errors
leds-gpio:
- add optional retain-state-shutdown DT property
- allow LED to retain state at shutdown
leds-tlc591xx:
- merge conditional tests
- add missing of_node_put
leds-powernv:
- delete an error message for a failed memory allocation in
powernv_led_create()
leds-is31fl32xx.c
- convert to using custom %pOF printf format specifier
Constify attribute_group structures in:
- leds-blinkm
- leds-lm3533
Make several arrays static const in:
- leds-aat1290
- leds-lp5521
- leds-lp5562
- leds-lp8501"
