From: Ville Syrjälä Date: Wed, 9 Apr 2014 10:29:08 +0000 (+0300) Subject: drm/i915: Don't use pipe_offset stuff for DPLL registers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2d401b175f9026d839d3ad1cf444802c986c32bc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Don't use pipe_offset stuff for DPLL registers These are just single registers so wasting space for the pipe offsets seems a bit pointless. So just use the _PIPE3() macro instead. Also rewrite the _PIPE3() macro to be more obvious, and protect the arguments properly.
