Subject: [PATCH] media: rkisp1: make const arrays ae_wnd_num and hist_wnd_num static
Date: Wed,  2 Nov 2022 15:51:17 +0000	[thread overview]
Message-ID: <20221102155117.144570-1-colin.i.king@gmail.com> (raw)

Don't populate the const arrays on the stack, instead make them
static. Also makes the object code smaller.
