Subject: [PATCH] ASoC: soc-pcm: fix the return value in dpcm_apply_symmetry()
Date: Mon, 14 Jun 2021 09:17:46 +0200 [thread overview]
Message-ID: <20210614071746.1787072-1-perex@perex.cz> (raw)
In case, where the loops are not executed for a reason, the uninitialized
variable 'err' is returned to the caller. Make code fully predictible
and assign zero in the declaration.
