From 92a11f9e7cb876e6cf9080e4a1642142cb9221b2 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 25 Apr 2005 07:55:57 -0700 Subject: [PATCH] [PATCH] ppc iomem annotations: ->io_base_virt * ->io_base_virt in struct pci_controller is iomem pointer. Marked as such. Most of the places that used it are already annotated to expect iomem. * places that did gratitious (and wrong) casts a-la isa_io_base = (unsigned long)ioremap(...); hose->io_base_virt = (void *)isa_io_base; turned into hose->io_base_virt = ioremap(...); isa_io_base = (unsigned long)hose->io_base_virt; * pci_bus_io_base() annotated as returning iomem pointer.
