USB: usbserial - fix potential deadlock between write() and IRQ USB: usbserial - fix potential deadlock between write() and IRQ usb_serial_generic_write() doesn't disable interrupts when taking port->lock, and could therefore deadlock with usb_serial_generic_read_bulk_callback() being called from interrupt, taking the same lock. Fix it. Signed-off-by: Jiri Kosina <jkosina@suse.cz> Acked-by: Larry Finger <larry.finger@lwfinger.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
