Subject: [PATCH 2/4] DRM: ARC: PGU: cleanup supported format list code
Date: Tue, 19 Nov 2019 17:41:45 +0300 [thread overview]
Message-ID: <20191119144147.8022-3-Eugeniy.Paltsev@synopsys.com> (raw)
In-Reply-To: <20191119144147.8022-1-Eugeniy.Paltsev@synopsys.com>
Get rid of 'simplefb_format' structure usage as we only use its
'fourcc' field.
