ASoC: mxs-saif: Fix refcount leak in mxs_saif_probe 

stable inclusion
from stable-v4.19.247
commit 30d110ca703ce60162ec337aa564a3e4da30715f
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP75W
CVE: CVE-2022-49482

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=30d110ca703ce60162ec337aa564a3e4da30715f



--------------------------------

[ Upstream commit 2be84f73 ]

of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
