It needs to be converted, but some of them didn't. This is bug, but this bug does nothing because these are using same value. This patch-set cleanup these.

Could we use this instead: enum snd_compr_direction { SND_COMPRESS_PLAYBACK = SNDRV_PCM_STREAM_PLAYBACK, SND_COMPRESS_CAPTURE = SNDRV_PCM_STREAM_CAPTURE }; Or remove this duplication completely and get rid of snd_compr_direction?

Yes I agree with you. I'm not sure why this duplication was created, but my patch tried to make it sane. If Mark can agree, I can post snd_compr_direction remove patch. Thank you for your help !!

Right, such uapi can't be removed. Essentially both compress and PCM definitions are identical, and can be never different because of ABI compatibility, which means it's safe to mix both variants in the code. If you're unsure, we may add BUILD_BUG_ON() to check the coincidence of both values. thanks, Takashi ^ permalink raw reply [flat|nested] 10+ messages in thread

Unless any strong type is used, it should be fine as is. BUILD_BUG_ON() would catch if the value is changed inconsistently. thanks, Takashi ^ permalink raw reply [flat|nested] 10+ messages in thread
