Calling ath_bus_cleanup() after ieee80211_free_hw() resulted in access to common->bus_ops, which is already freed as part of the device data. Remove the cleanup field in struct ath_bus_ops, as it was never used properly. Remove ath_bus_cleanup(). Merge cleanup functions in place of the ath_bus_cleanup() calls. Take care not to use any device data after ieee80211_free_hw(). Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
