USB: last abuses of intfdata in close for usb-serial drivers
these drivers abused intfdata in close() as flags for binding. That races with reprobing of those devices. This patch fixes that by using the flag and the locks introduced with the patch against mos7720. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
