cfg80211: fix memory leak of wiphy device name
In wiphy_new_nm(), if an error occurs after dev_set_name() and device_initialize() have already been called, it's necessary to call put_device() (via wiphy_free()) to avoid a memory leak. Reported-by: syzbot+7fddca22578bc67c3fe4@syzkaller.appspotmail.com Fixes: 1f87f7d3a3b4 ("cfg80211: add rfkill support") Cc: stable@vger.kernel.org Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
