From 09d118008f9815181d2114b84800e68019cd7b7d Mon Sep 17 00:00:00 2001 From: Ola Olsson Date: Sun, 13 Dec 2015 19:12:03 +0100 Subject: nl80211: fix a few memory leaks in reg.c The first leak occurs when entering the default case in the switch for the initiator in set_regdom. The second leaks a platform_device struct if the platform registration in regulatory_init succeeds but the sub sequent regulatory hint fails due to no memory.
