Merge tag 'led_fixes_for_4.12-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED fixes from Jacek Anaszewski:
"Two LED fixes:
- fix signal source assignment for leds-bcm6328
- revert patch that intended to fix LED behavior on suspend but it
had a side effect preventing suspend at all due to uevent being
sent on trigger removal"
* tag 'led_fixes_for_4.12-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds:
Revert "leds: handle suspend/resume in heartbeat trigger"
leds: bcm6328: fix signal source assignment for leds 4 to 7
