Subject: [PATCH 5.10 265/390] powerpc/sysdev/fsl_msi: Add missing of_node_put()

From: Liang He <windhl@....com>

[ Upstream commit def435c04ee984a5f9ed2711b2bfe946936c6a21 ]

In fsl_setup_msi_irqs(), use of_node_put() to drop the reference
returned by of_parse_phandle().

Fixes: 895d603f945ba ("powerpc/fsl_msi: add support for the fsl, msi property in PCI nodes")
