Subject: [PATCH 00/11] improve the fb_setcmap helper

Hi!

While trying to get CLUT support for the atmel_hlcdc driver, and
specifically for the emulated fbdev interface, I received some
push-back that my feeble in-driver attempts should be solved
by the core. This is my attempt to do it right.

Boris and Daniel, was this approximately what you had in mind?

I have obviously not tested all of this with more than a compile,
but the first patch is enough to make the atmel-hlcdc driver
do what I need. The rest is just lots of removals and cleanup
made possible by the improved core.

Please test, I would not be surprised if I have fouled up some
bit-manipulation somewhere in this mostly mechanical change...

Cheers,
peda
