From 66a89b2164e2d30661edbd1953eacf0594d8203a Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 9 Aug 2011 11:10:56 -0400 Subject: hwmon: (ibmaem) add missing kfree rs_resp is dynamically allocated in aem_read_sensor(), so it should be freed before exiting in every case. This collects the kfree and the return at the end of the function.
