Subject: counter: intel-qep: Use devm_mutex_init()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ca815bb87064a8f68b00eaf8872ef0d4a33a5bf7;p=thirdparty%2Flinux.git

counter: intel-qep: Use devm_mutex_init()

intel_qep_probe() calls mutex_init() but lacks the pairing
mutex_destroy() calls. Convert to devm_mutex_init() which handles
cleanup automatically.
