fb: fix atyfb build warning
PATCH 1/2 fb: fix atyfb build warning
From: Randy Dunlap <[email protected]>
Fix build warning when neither of CONFIG_FB_ATY_GX or CONFIG_FB_ATY_CT is enabled, since ARRAY_SIZE(aty_chips) is 0 in that case.
drivers/video/aty/atyfb_base.c:437:11: warning: overflow in implicit constant conversion [-Woverflow]
