Subject: [PATCH 04/31] video: fbdev: aty: atyfb_base: Mark 'dac_type' as __maybe_unused

'dac_type' is only used in the '#ifdef CONFIG_ATARI' clause.

Fixes the following W=1 kernel build warning(s):

 drivers/video/fbdev/aty/atyfb_base.c: In function ‘aty_init’:
 drivers/video/fbdev/aty/atyfb_base.c:2363:6: warning: variable ‘dac_type’ set but not used [-Wunused-but-set-variable]
