Patch against mainline.

Subject: [PATCH] backlight: constify backlight_ops

backlight_device_register already expects a const "ops" argument,
so let's make the backlight_ops instances const.

Inspired by hunks of the grsecurity patch, updated for newer kernels.
Even though backlight_ops is already part of the list of "should be const"
operations structures of 2.6.35 checkpatch.pl, one non-const struct instance
constified by this patch has been added after 2.6.35.
