Subject: drm/i915: enable IPS for bpp <= 24
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b6dfdc9b7f0d7859ea146b6c869aa2cfe6d713f3;p=linux-beck.git

drm/i915: enable IPS for bpp <= 24

Art confirms that this should work fine.  Since most panels are 18bpp
with dithering from 24bpp, the existing code wouldn't be enabled in most
cases.
