staging: dgnc: UART_IIR_XOFF code is buggy
The UART_IIR_XOFF was supposed to be a no-op but, because there was a missing semi-colon, the if statement is not "Empty". I have just deleted this code because it was supposed to be a no-op anyway. UART_IIR_XOFF is a standard define and not something specific to this driver. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
