From 97e87f8ebe978e881c7325ba490574bd5500b133 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 11 Jun 2009 12:29:27 +0100 Subject: tty: cyclades, plx9060 casts cleanup Remove ugly all-over-the-code casts of ctl_addr to 9060 space. Add an union to the cyclades_card structure, which contains a pointer to both 9050 and 9060 spaces. The 9050 space layout is unknown, so let it still as a void __iomem pointer.
