Subject: staging: vboxvideo: remove dead gamma lut code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=25ff38ca79a9336ea34cc0d0b0b0b39ad7836d28;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

staging: vboxvideo: remove dead gamma lut code

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.
