drm/i915: Always use crtc_ timings when dealing with adjustead_mode
The adjustead_mode crtc_ timings are what we will program into the hardware, so it's those timings we should be looking practically everywhere. The normal and crtc_ timings should differ only when stere doubling is used. In that case the normal timings are the orignal non-doubled timigns, and crtc_ timings are the doubled timings used by the hardware. The only case where we continue to look at the normal timings is when we pass the adjusted_mode to drm_match_{cea,hdmi}_mode() to find the VIC. drm_edid keeps the modes aronund in the non-double form only, so it needs the non-double timings to match against. Done with sed 's/adjusted_mode->\([vhVH]\)/adjusted_mode->crtc_\1/g' 's/adjusted_mode->clock/adjusted_mode->crtc_clock/g' with a manual s/VDisplay/vdisplay/ within the comment in intel_dvo.c v2: Update due to intel_dsi.c changes Reviewed-by: Mika Kahola <mika.kahola@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
