[PATCH] INPUT: Delete unused source file drivers/input/power.c.

[PATCH] INPUT: Delete unused source file drivers/input/power.c.

[Robert P. J. Day]

Delete the never-compiled source file drivers/input/power.c, and
remove its entry from the corresponding Makefile, as there is no
Kconfig file that refers to the config option INPUT_POWER.

Please cc the maintainer when he's this easy to find ;)

There are significant-looking patches against input.c in the git-input
tree - if it's presently dead I suspect that it'll be coming back to
life soon.

Actually it is just me being anal and trying to keep even dead modules
compilable... I think it is time for power.c to go. Now that we have ACPI
using input layer to report buttons/lid I don't see it coming back.

ok, i was just going by the total lack of reference and date of 2001
in the source file.
