From: Tejun Heo Date: Tue, 11 Mar 2008 10:52:31 +0000 (+0900) Subject: ahci: request all PCI BARs X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dea55137634226fd74d5187a15dee1244ec252cb;p=linux-beck.git ahci: request all PCI BARs ahci is often implemented with accompanying SFF compatible interface and legacy IDE driver may attach to the legacy IO ports when the controller is already claimed by ahci and vice-versa. This patch makes ahci use pcim_iomap_regions_request_all() so that all IO regions are claimed on attach.
