Subject[PATCH] drivers/video/fbdev/atyfb: make const arrays static, reduces object code size
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the const arrays ragepro_tbl and ragexl_tbl on the stack,
instead make them static. Makes the object code smaller by over 380 bytes:

Before:
text data bss dec hex filename
41089 10592 768 52449 cce1 atyfb_base.o

After:
text data bss dec hex filename
40544 10752 768 52064 cb60 atyfb_base.o

(gcc version 7.2.0, x86_64)
