Sure, just need to known which one i should tag... I saw that you are discussing with Lee by default i ack both, i let you decide which one will be merged :) Acked-by: Arnaud Pouliquen <arnaud.pouliquen@st.com> > >> Regards, >> Arnaud >> >>> --- >>> sound/soc/sti/uniperif.h | 2 +- >>> 1 file changed, 1 insertion(+), 1 deletion(-) >>> >>> diff --git a/sound/soc/sti/uniperif.h b/sound/soc/sti/uniperif.h >>> index 2dc2da5d458b..a16adeb7c1e9 100644 >>> --- a/sound/soc/sti/uniperif.h >>> +++ b/sound/soc/sti/uniperif.h >>> @@ -1348,7 +1348,7 @@ struct sti_uniperiph_data { >>> struct sti_uniperiph_dai dai_data; >>> }; >>> >>> -static const struct snd_pcm_hardware uni_tdm_hw = { >>> +static __maybe_unused const struct snd_pcm_hardware uni_tdm_hw = { >>> .info = SNDRV_PCM_INFO_INTERLEAVED | SNDRV_PCM_INFO_BLOCK_TRANSFER | >>> SNDRV_PCM_INFO_PAUSE | SNDRV_PCM_INFO_MMAP | >>> SNDRV_PCM_INFO_MMAP_VALID, >>>

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: ‘uni_tdm_hw’ defined but not used [-Wunused-const-variable=] 1351 | static const struct snd_pcm_hardware uni_tdm_hw = { | ^~~~~~~~~~ Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> --- sound/soc/sti/uniperif.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
