Subject: [alsa-devel] [PATCH] ALSA: uapi: Fix sparse warning
Date: Wed, 29 Jan 2020 10:44:48 -0800	[thread overview]
Message-ID: <20200129184448.3005-1-ranjani.sridharan@linux.intel.com> (raw)

Fix the following sparse warning generated due to
64-bit compat type having fields defined explicitly
with __32:
sound/soc/sof/sof-audio.c:46:31: warning: incorrect type in assignment (different base types)
sound/soc/sof/sof-audio.c:46:31: expected restricted snd_pcm_state_t [usertype] state
sound/soc/sof/sof-audio.c:46:31: got signed int [usertype] state
