[alsa-devel] [PATCH 2/6] ALSA: pcm: Fix return code in pcm_native.c

[Sachin Kamat]

Return the value obtained from snd_pcm_hw_constraint_minmax() instead
of -EINVAL. Silences the following smatch warning:
sound/core/pcm_native.c:2003 snd_pcm_hw_constraints_complete() info:
why not propagate 'err' from snd_pcm_hw_constraint_minmax() instead of -22?

Build tested and based on linux-next 20121115.
