Subject: [Intel-gfx] [PATCH] drm/i915/hdmi: prefer to_i915() over drm->dev_private to get at i915
Date: Tue, 11 Feb 2020 15:44:27 +0200	[thread overview]
Message-ID: <20200211134427.31605-1-jani.nikula@intel.com> (raw)

drm->dev_private is to be avoided. Use to_i915() on the struct
drm_device pointer instead. Rename the affected local dev_priv variables
to i915 while at it.
