Subject: [PATCH 09/21] drm/i915/gtt: Rename unmap_and_free_px to free_px
Date: Fri, 22 May 2015 20:05:02 +0300	[thread overview]
Message-ID: <1432314314-23530-10-git-send-email-mika.kuoppala@intel.com> (raw)
In-Reply-To: <1432314314-23530-1-git-send-email-mika.kuoppala@intel.com>

All the paging structures are now similar and mapped for
dma. The unmapping is taken care of by common accessors, so
don't overload the reader with such details.
