Merge branch 'mtd-nand-trigger' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds into nand/next

Pull leds-trigger changes from Jacek Anaszewski.
Create a generic mtd led-trigger to replace the exisitng nand led-trigger
implementation.

* 'mtd-nand-trigger' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds:
  mtd: Hook I/O activity to the MTD LED trigger
  mtd: nand: Remove the "nand-disk" LED trigger
  leds: trigger: Introduce a MTD (NAND/NOR) trigger
  mtd: Uninline mtd_write_oob and move it to mtdcore.c
  leds: trigger: Introduce a kernel panic LED trigger
