[PATCH AUTOSEL 5.6 11/79] ASoC: topology: Check return value of pcm_new_ver

[Sasha Levin]

From: Amadeusz Sławiński <amadeuszx.slawinski at linux.intel.com>

[ Upstream commit b3677fc3d68dd942c92de52f0bd9dd8b472a40e6 ]

Function pcm_new_ver can fail, so we should check it's return value and
handle possible error.
