mac80211: check interface is down before type change
For some strange reason the netif_running() check ended up after the actual type change instead of before, potentially causing all kinds of problems if the interface is up while changing the type; one of the problems manifests itself as a warning: WARNING: at net/mac80211/iface.c:651 ieee80211_teardown_sdata+0xda/0x1a0 [mac80211]() Hardware name: Aspire one Pid: 2596, comm: wpa_supplicant Tainted: G W 2.6.31-10-generic #32-Ubuntu Call Trace: [] warn_slowpath_common+0x6d/0xa0 [] warn_slowpath_null+0x15/0x20 [] ieee80211_teardown_sdata+0xda/0x1a0 [mac80211] [] ieee80211_if_change_type+0x4a/0xc0 [mac80211] [] ieee80211_change_iface+0x61/0xa0 [mac80211] [] cfg80211_wext_siwmode+0xc7/0x120 [cfg80211] [] ioctl_standard_call+0x58/0xf0 (http://www.kerneloops.org/searchweek.php?search=ieee80211_teardown_sdata) Cc: Arjan van de Ven <arjan@infradead.org> Cc: stable@kernel.org Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
