From: Colin Ian King <redacted> Don't populate const arrays on the stack, instead make them static. Makes the object code smaller by nearly 400 bytes: Before: text data bss dec hex filename 15164 6336 0 21500 53fc drivers/video/backlight/s6e63m0.o After: text data bss dec hex filename 14669 6432 0 21101 526d drivers/video/backlight/s6e63m0.o Signed-off-by: Colin Ian King <redacted> --- drivers/video/backlight/s6e63m0.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
