Subject: linux-next: manual merge of the leds tree with the drivers-x86 tree

Hi Jacek,

Today's linux-next merge of the leds tree got a conflict in:

  drivers/platform/x86/dell-laptop.c

between commit:

  573eedacfba3 ("platform/x86: dell-*: Call new led hw_changed API on kbd brightness change")

from the drivers-x86 tree and commit:

  44319ab7e0ed ("platform/x86: dell-laptop: import dell_micmute_led_set() from drivers/leds/dell-led.c")

from the leds tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
