From 4ec16da733b81b64e9c7823fd2ea506131013a8f Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 9 Apr 2013 05:43:33 -0300 Subject: [media] rc: winbond-cir: fix potential double free in wbcir_probe() Since rc_unregister_device() frees its argument, the subsequently call to rc_free_device() on the same variable will cause a double free bug. Fix by set argument to NULL, thus when fall through to rc_free_device(), nothing will be done there.
