This patch is to disable the USB ports unconnected to USB3503. In order to disable the port, 'port_off_mask' must be set. * Disable PORT1 only .port_off_mask = USB3503_OFF_PORT1; * Disable PORT1 and PORT3 only .port_off_mask = USB3503_OFF_PORT1 | USB3503_OFF_PORT3; * Enables all ports .port_off_mask = 0; Signed-off-by: Dongjin Kim <tobetter@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
