[RESEND PATCH] staging: vboxvideo: remove dead gamma lut code

From: Peter Rosin
Date: Fri Aug 04 2017 - 06:45:27 EST


The redundant fb helpers .load_lut, .gamma_set and .gamma_get are
no longer used. Remove the dead code that was not doing anything
sensible anyway.

Hi Daniel,

Here it goes, but do you really need me to resend v5 14/14?

Cheers,
