From 1624f003349b49050f42c7d9f5407dfc05efb912 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 4 Jan 2006 18:09:44 +0000 Subject: [PATCH] [SERIAL] Fix matching of MMIO ports The function uart_match_port() incorrectly compares the ioremap'd virtual addresses of ports instead of the physical address to find duplicate ports for MMIO based UARTs. This fixes it.
