Subject: [PATCH] arch: powerpc: platforms: 85xx: Fix refcount leak bug in ksi8560.c
Date: Thu, 16 Jun 2022 21:29:22 +0800 [thread overview]
Message-ID: <20220616132922.3987053-1-windhl@126.com> (raw)
In ksi8560_setup_arch(), of_find_compatible_node() will return a
node pointer with refcount incremented. We should use of_node_put()
when it is not used anymore.
