A locking problem was found in routine _rtl92ee_cmd_send_packet() that led to system freezes. Upon inspection, several drivers had the same problem; however, the routines all used the same code. The common code has been moved into rtlwifi. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
