Subject: [PATCH 5.15 686/917] ASoC: rsnd: Fix an error handling path in rsnd_node_count()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 173632358fde7a567f28e07c4549b959ee857986 ]

If we return before the end of the 'for_each_child_of_node()' iterator, the
reference taken on 'np' must be released.

Add the missing 'of_node_put()' call.

Fixes: c413983eb66a ("ASoC: rsnd: adjust disabled module")
