Subject: [PATCH 35/36] drm/udl: use bpp instead of cpp for drm_format_info
Date:   Mon, 23 Sep 2019 20:53:49 +0800
Message-Id: <1569243230-183568-5-git-send-email-hjc@rock-chips.com>
In-Reply-To: <1569243230-183568-1-git-send-email-hjc@rock-chips.com>
References: <1569243230-183568-1-git-send-email-hjc@rock-chips.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

cpp[BytePerPlane] can't describe the 10bit data format correctly,
So we use bpp[BitPerPlane] to instead cpp.
