[Intel-gfx] [PATCH 16/20] drm/i915: Use crtc_clock with the adjusted mode
Damien Lespiau
damien.lespiau at intel.com
Thu Sep 19 18:40:31 CEST 2013
struct drm_mode_display now has a separate crtc_ version of the clock to
be used when we're talking about the timings given to the harwadre (was
far as the mode is concerned).
This commit is really the result of a git grep adjusted_mode.*clock and
replacing those by adjusted_mode.crtc_clock. No functional change.
