Subject: cfg80211: avoid using default in interface type switch
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=de4fcbadde68e3429cc533c29abf6fbceda4628f;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

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.
