Subject: [PATCH] scsi: ufs: ufs-exynos: make a const array static, makes object smaller
Date: Wed, 5 May 2021 20:01:04 +0100 [thread overview]
Message-ID: <20210505190104.70112-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the const array granularity_tbl on the stack but instead it
static. Makes the object code smaller by 190 bytes:
Before:
text data bss dec hex filename
25563 6908 0 32471 7ed7 ./drivers/scsi/ufs/ufs-exynos.o
After:
text data bss dec hex filename
25213 7068 0 32281 7e19 ./drivers/scsi/ufs/ufs-exynos.o
(gcc version 10.3.0)
