Subject: [PATCH] media: platform: replace ternary operator with max()
Date: Fri, 13 May 2022 21:32:55 +0800	[thread overview]
Message-ID: <20220513133255.58600-1-guozhengkui@vivo.com> (raw)

Fix the following coccicheck warning:

drivers/media/platform/samsung/s5p-jpeg/jpeg-core.c:1712:24-25:
WARNING opportunity for max()

max() macro is defined in include/linux/minmax.h. It avoids multiple
evaluations of the arguments when non-constant and performs strict
type-checking.
