Subject: [PATCH v10 12/28] media: platform: Use generic rounding helpers
Date: Thu, 23 Jul 2020 11:04:35 +0800	[thread overview]
Message-ID: <20200723030451.5616-13-xia.jiang@mediatek.com> (raw)
In-Reply-To: <20200723030451.5616-1-xia.jiang@mediatek.com>

Use clamp() to replace mtk_jpeg_bound_align_image() and round() to
replace mtk_jpeg_align().
