Subject: [PATCH v2 2/3] media: rkisp1: Make local immutable array variables static const
Date: Thu, 17 Nov 2022 17:42:16 +0900	[thread overview]
Message-ID: <20221117084217.3892680-3-paul.elder@ideasonboard.com> (raw)
In-Reply-To: <20221117084217.3892680-1-paul.elder@ideasonboard.com>

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

The max_widths and max_heights variables in rkisp1_try_fmt() are
immutable and don't need to be allocated on the stack every time the
function is called. Make them static.
