From: Arjan van de Ven Date: Tue, 21 Oct 2008 04:46:01 +0000 (-0700) Subject: USB: use pci_ioremap_bar() in drivers/usb X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8e8ce4b642ce4beb865fb1d67cd8ea883d9ae7d7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git USB: use pci_ioremap_bar() in drivers/usb 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.
