serial: Fix sparse warnings in uart_throttle()/uart_unthrottle()
The struct uart_port.flags field is type upf_t, as are the matching bit definitions. Change local mask variable to type upf_t. Fixes sparse warnings: drivers/tty/serial/serial_core.c:620:22: warning: invalid assignment: |= drivers/tty/serial/serial_core.c:620:22: left side has type unsigned int drivers/tty/serial/serial_core.c:620:22: right side has type restricted upf_t drivers/tty/serial/serial_core.c:622:22: warning: invalid assignment: |= drivers/tty/serial/serial_core.c:622:22: left side has type unsigned int drivers/tty/serial/serial_core.c:622:22: right side has type restricted upf_t drivers/tty/serial/serial_core.c:624:17: warning: restricted upf_t degrades to integer drivers/tty/serial/serial_core.c:626:22: warning: invalid assignment: &= drivers/tty/serial/serial_core.c:626:22: left side has type unsigned int drivers/tty/serial/serial_core.c:626:22: right side has type restricted upf_t drivers/tty/serial/serial_core.c:629:20: warning: restricted upf_t degrades to integer drivers/tty/serial/serial_core.c:632:20: warning: restricted upf_t degrades to integer drivers/tty/serial/serial_core.c:643:22: warning: invalid assignment: |= drivers/tty/serial/serial_core.c:643:22: left side has type unsigned int drivers/tty/serial/serial_core.c:643:22: right side has type restricted upf_t drivers/tty/serial/serial_core.c:645:22: warning: invalid assignment: |= drivers/tty/serial/serial_core.c:645:22: left side has type unsigned int drivers/tty/serial/serial_core.c:645:22: right side has type restricted upf_t drivers/tty/serial/serial_core.c:647:17: warning: restricted upf_t degrades to integer drivers/tty/serial/serial_core.c:649:22: warning: invalid assignment: &= drivers/tty/serial/serial_core.c:649:22: left side has type unsigned int drivers/tty/serial/serial_core.c:649:22: right side has type restricted upf_t drivers/tty/serial/serial_core.c:652:20: warning: restricted upf_t degrades to integer drivers/tty/serial/serial_core.c:655:20: warning: restricted upf_t degrades to integer Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
