[PATCH 3/3] ARM: at91: pm: put node after its usage

From: Claudiu Beznea
Date: Mon Aug 03 2020 - 03:25:37 EST


of_find_matching_node_and_match() returns a node pointer with refcount
incremented. Use of_node_put() after the node has been used.

Fixes: 13f16017d3e3f ("ARM: at91: pm: Tie the USB clock mask to the pmc")
