From arjan@infradead.org Mon Oct 27 11:23:04 2008 From: Arjan van de Ven Date: Mon, 20 Oct 2008 21:46:01 -0700 Subject: USB: use pci_ioremap_bar() in drivers/usb To: greg@kroah.com, linux-usb@vger.kernel.org Message-ID: <20081020214601.21b6952c@infradead.org> From: Arjan van de Ven Use the newly introduced pci_ioremap_bar() function in drivers/usb. pci_ioremap_bar() just takes a pci device and a bar number, with the goal of making it really hard to get wrong, while also having a central place to stick sanity checks.
