Subject: [PATCH] ASoC: mt6359: Fix refcount leak bug
Git-commit: a8d5df69e2ec702d979f7d04ed519caf8691a032
Patch-mainline: v6.0-rc1
References: git-fixes

In mt6359_parse_dt() and mt6359_accdet_parse_dt(), we should call
of_node_put() for the reference returned by of_get_child_by_name()
which has increased the refcount.

Fixes: 683530285316 ("ASoC: mt6359: fix failed to parse DT properties")
Fixes: eef07b9e0925 ("ASoC: mediatek: mt6359: add MT6359 accdet jack driver")
