From de4fcbadde68e3429cc533c29abf6fbceda4628f Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 31 Oct 2014 14:16:12 +0100 Subject: [PATCH] cfg80211: avoid using default in interface type switch Most code avoids having a default case in interface type switch statements already, to make it easier to find places that need to be extended. Change the code in the __cfg80211_leave() and nl80211_key_allowed() functions to not have a default case.
