Subject: [alsa-devel] [PATCH 10/10] ALSA: xen: Use standard
pcm_format_to_bits() for ALSA format bits
Message-ID: <20180725211945.19222-11-ti...@suse.de>
The open codes with the bit shift in xen_snd_front_alsa.c give sparse
warnings as the PCM format type is with __bitwise.
There is already a standard macro to get the format bits, so let's use
it instead.
This fixes sparse warnings like:
sound/xen/xen_snd_front_alsa.c:191:47: warning: restricted snd_pcm_format_t
degrades to integer
