[Intel-gfx] [PATCH 09/10] drm/i915: Clean up PPS code calling conventions
Ville Syrjala
ville.syrjala at linux.intel.com
Tue Oct 31 20:51:22 UTC 2017
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
No need to pass 'dev' or 'dev_priv' when the function already takes
'intel_dp'. Also let's prefer passing 'dev_priv' instead of 'dev'
when we have to pass one or the other.
