The previously added stubs for aty_{ld,}st_lcd() make it so that these functions are used regardless of the config options that were guarding them, so remove the #ifdef/#endif lines and make their declarations always visible. This fixes build warnings that were reported by clang:
drivers/video/fbdev/aty/atyfb_base.c:180:6: warning: no previous prototype for function 'aty_st_lcd' [-Wmissing-prototypes] void aty_st_lcd(int index, u32 val, const struct atyfb_par *par) ^ drivers/video/fbdev/aty/atyfb_base.c:180:1: note: declare 'static' if the function is not intended to be used outside of this translation unit void aty_st_lcd(int index, u32 val, const struct atyfb_par *par)
drivers/video/fbdev/aty/atyfb_base.c:183:5: warning: no previous prototype for function 'aty_ld_lcd' [-Wmissing-prototypes] u32 aty_ld_lcd(int index, const struct atyfb_par *par) ^ drivers/video/fbdev/aty/atyfb_base.c:183:1: note: declare 'static' if the function is not intended to be used outside of this translation unit u32 aty_ld_lcd(int index, const struct atyfb_par *par)
They should not be marked as static since they are used in mach64_ct.c.
