Subject: cpufreq: scmi: Fix device_node reference leak in scmi_cpu_domain_id()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0b7fbf9333fa4699a53145bad8ce74ea986caa13;p=thirdparty%2Flinux.git

cpufreq: scmi: Fix device_node reference leak in scmi_cpu_domain_id()

When calling of_parse_phandle_with_args(), the caller is responsible
to call of_node_put() to release the reference of device node.
In scmi_cpu_domain_id(), it does not release the reference.
