Subject: [PATCH 2/4] media: hantro: Simplify buffer helpers
Date: Tue,  3 Sep 2019 15:17:09 -0300	[thread overview]
Message-ID: <20190903181711.7559-3-ezequiel@collabora.com> (raw)
In-Reply-To: <20190903181711.7559-1-ezequiel@collabora.com>

Modify hantro_get_ref() and hantro_h264_get_ref_buf() helpers
to return the buffer DMA address, this makes the code simpler
and at the same time will allow easier enablement of the
post-processing feature.
