[PATCH] drm/mgag200: make array m_div_val static, shrinks object size

From: Colin King
Date: Thu Nov 29 2018 - 18:40:55 EST


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

Don't populate the const array m_div_val on the stack but instead
make it static. Makes the object code smaller by 60 bytes:

Before:
text data bss dec hex filename
32339 1728 0 34067 8513 mgag200/mgag200_mode.o

After:
text data bss dec hex filename
32215 1792 0 34007 84d7 mgag200/mgag200_mode.o

(gcc version 8.2.0 x86_64)
