[PATCH] [media] exynos4-is: make array 'cmd' static, shrinks object size

From: Colin King
Date: Sat Jan 06 2018 - 11:03:36 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the const read-only array 'cmd' on the stack but instead
make it static. Makes the object code smaller by 38 bytes:

Before:
text data bss dec hex filename
4950 868 0 5818 16ba fimc-is-regs.o

After:
text data bss dec hex filename
4824 956 0 5780 1694 fimc-is-regs.o

(gcc version 7.2.0 x86_64)
