Subject: [PATCH] arm: mach-imx: Add missing of_node_put() in cpu-imx31.c
Date: Wed, 15 Jun 2022 22:54:48 +0800 [thread overview]
Message-ID: <20220615145448.3969508-1-windhl@126.com> (raw)
In mx31_read_cpu_rev(), of_find_compatible_node() will return a
node pointer with refcount incremented. We should use of_node_put()
when it is not used anymore.
