Subject: serial: xuartps: Fix iobase use.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0c39a467e7ba68a0d94439c1ebe260dc5b26302b;p=linux-beck.git

serial: xuartps: Fix iobase use.

cdns_uart_get_port() sets port->iobase = 1 to "mark port in use", but
this "in use" condition is not checked anywhere else in the code. So
remove the line, keeping port->iobase = 0 (which also makes more sense).
