[Michal Simek]

From: Nava kishore Manne <nava.ma...@xilinx.com>

Trivial patch which fixes this checkpatch warning:
WARNING: Avoid multiple line dereference - prefer 'port->state->xmit.tail'
+                               port->state->xmit.buf[port->state->xmit.
+                               tail], port->membase + CDNS_UART_FIFO);
