Subject: [PATCH] ASoC: soc-pcm: fix the return value in dpcm_apply_symmetry()
Date: Mon, 14 Jun 2021 09:17:46 +0200
Message-ID: <> (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.
