From cdbd3865acc2e98a349b41d130985e6f5f2dfc19 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Mon, 15 Oct 2007 19:34:37 +1000 Subject: Use dcr_host_t.base in dcr_unmap() With the base stored in dcr_host_t, there's no need for callers to pass the dcr_n into dcr_unmap(). In fact this removes the possibility of them passing the incorrect value, which would then be iounmap()'ed.
