Subject: [PATCH] ARM: OMAP2+: Fix refcount leak in omap_gic_of_init
Date: Wed, 9 Mar 2022 10:43:01 +0000 [thread overview]
Message-ID: <20220309104302.18398-1-linmq006@gmail.com> (raw)
The of_find_compatible_node() function returns a node pointer with
refcount incremented, We should use of_node_put() on it when done
Add the missing of_node_put() to release the refcount.
Fixes: fd1c07861491 ("ARM: OMAP4: Fix the init code to have OMAP4460 errata available in DT build")
