Subject: ALSA: pcm: Fix return code in pcm_native.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6cf95152079d7c6d7ba6442be45e02b24bbb1c65;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: pcm: Fix return code in pcm_native.c

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?
