Subject: [PATCH] media: staging: rkisp1: rsz: make const array static, makes object smaller
Date: Tue, 20 Oct 2020 15:46:55 +0100 [thread overview]
Message-ID: <20201020144655.53251-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the const array dev_names on the stack but instead it
static. Makes the object code smaller by 15 bytes.
Before:
text data bss dec hex filename
17091 2648 64 19803 4d5b media/rkisp1/rkisp1-resizer.o
After:
text data bss dec hex filename
17012 2712 64 19788 4d4c media/rkisp1/rkisp1-resizer.o
(gcc version 10.2.0)
