Subject: powerpc/maple: Add missing of_node_put() in time.c
X-Git-Tag: v6.1-rc1~103^2~179
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=23b1481898ee8704394cead67eae2634003f7ca8;p=thirdparty%2Flinux.git

powerpc/maple: Add missing of_node_put() in time.c

In maple_get_boot_time(), of_find_compatible_node() will return
a node pointer with refcount incremented. The reference should be
dropped with of_node_put() when it is not used anymore.
