Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds

Pull LED updates from Jacek Anaszewski:
 "In this merge cycle we had an interaction with MTD subsystem, that
  included converting drivers/mtd/nand/nand_base.c to use newly
  introduced MTD (NAND/NOR) LED trigger instead of implementing it on
  its own.

  Related MTD patches are intended to be merged through the LED tree,
  before MTD tree is merged, since further MTD development is based on
  those modifications.

  Summary:

  LEDs:
   - Introduce a kernel panic LED trigger

   - Introduce a MTD (NAND/NOR) trigger

   - led-tca6507: silence an uninitialized variable warning

   - ledtrig-ide-disk: Move ide_blink_delay to ledtrig_ide_activity()

   - leds-ss4200: Add depend on x86 arch

   - leds-ss4200: add DMI data for FSC SCALEO Home Server

   - leds-triggers: Allow to switch the trigger to "panic" on a kernel panic

   - devicetree: leds: Introduce "panic-indicator" optional property

   - leds-gpio: Support the "panic-indicator" firmware property

  MTD:
   - Uninline mtd_write_oob and move it to mtdcore.c

   - Remove the "nand-disk" LED trigger

   - Hook I/O activity to the MTD LED trigger"
