[PATCH v4 01/10] ASoC: sti: uniperif: fix 'defined by not used' warning

From: Pierre-Louis Bossart
Date: Thu Jul 09 2020 - 12:23:44 EST


Fix W=1 warning. The table uni_tdm_hw is declared in a header included
by multiple C file. This isn't really a good practice but for now
using __maybe_unused makes the following warning go away.

sound/soc/sti/sti_uniperif.c:12:
sound/soc/sti/uniperif.h:1351:38: warning: âuni_tdm_hwâ defined but
not used [-Wunused-const-variable=]
1351 | static const struct snd_pcm_hardware uni_tdm_hw = {
| ^~~~~~~~~~
