Subject: [PATCH] arm: mach-omap2: omap4-common: Fix refcount leak bug
Date: Fri, 17 Jun 2022 11:55:48 +0800 [thread overview]
Message-ID: <20220617035548.4003393-1-windhl@126.com> (raw)
In omap4_sram_init(), of_find_compatible_node() will return a node
pointer with refcount incremented. We should use of_node_put() when
it is not used anymore.
