[Intel-gfx] [PATCH v2 3/7] drm/i915: s/mode/adjusted_mode/ in functions that really get passed the adjusted_mode

Fri Sep 25 06:37:43 PDT 2015


From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Rename the function argument to 'adjusted_mode' whenever the function
only ever gets passed the adjusted_mode.

v2: Update due to intel_dsi.c changes
