Only 2 of the 3 source files which include this headerfile actually reference 'uni_tdm_hw'. The other source file 'sti_uniperif.c' sees as it as being unused. Mark it as __maybe_unused to show that this behaviour is not only known, it's intentional.
Fixes the following W=1 kernel build warning(s):
sound/soc/sti/uniperif.h:1351:38: warning: ‘uni_tdm_hw’ defined but not used [-Wunused-const-variable=] 1351 | static const struct snd_pcm_hardware uni_tdm_hw = { | ^~~~~~~~~~
