[PATCH 23/31] video: fbdev: s1d13xxxfb: Mark debug variables as __maybe_unused

From: Lee Jones
Date: Wed Jan 13 2021 - 09:53:13 EST


Can't declare these under the same clause as their use, since
debugging is enabled manually with an '#if {0,1}', so mark them as
__maybe_unused instead to notify the compiler that this behaviour is
expected.

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

drivers/video/fbdev/s1d13xxxfb.c: In function ‘s1d13xxxfb_fetch_hw_state’:
drivers/video/fbdev/s1d13xxxfb.c:644:16: warning: variable ‘is_dual’ set but not used [-Wunused-but-set-variable]
drivers/video/fbdev/s1d13xxxfb.c:643:11: warning: variable ‘lcd_bpp’ set but not used [-Wunused-but-set-variable]
