[PATCH AUTOSEL 4.19 18/19] fsi: master-ast-cf: Fix missing of_node_put in fsi_master_acf_probe

[Sasha Levin]

From: Lv Ruyi <lv.ruyi@xxxxxxxxxx>

[ Upstream commit 182d98e00e4745fe253cb0c24c63bbac253464a2 ]

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