Merge tag 'leds_for_4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds

Pull LED updates from Jacek Anaszewski:
 "New LED class driver:
   - add driver for Mellanox regmap LEDs

  Improvement to ledtrig-disk:
   - extend disk trigger for reads and writes

  Improvements and fixes to existing LED class drivers:
   - add more product/board names for PC Engines APU2
   - fix wrong dmi_match on PC Engines APU LEDs
   - clarify chips supported by LM355x driver
   - fix Kconfig text for MLXCPLD, SYSCON, MC13783, NETXBIG
   - allow leds-mlxcpld compilation for 32 bit arch"
