Subject[PATCH -next 0/2] leds: add substitutes for /sys/class/leds/<led>/trigger
Date
Reading /sys/class/leds/<led>/trigger returns all available LED triggers.
However, this violates the "one value per file" rule of sysfs.

This series provides a new /sys/devices/virtual/led-trigger/ directory and
/sys/class/leds/<led>/current-trigger. The new api follows the "one value
per file" rule of sysfs.

This series was previously developed as a part of the series "leds: fix
/sys/class/leds/<led>/trigger and add new api" [1]. Now this version
only contains the new api part.
