From 53637c911b7a2397b50690cd67b7d59145bcae9c Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Fri, 8 Apr 2016 09:21:12 -0700 Subject: [PATCH] arc: Add virt_to_phys() stub Commit cf7c93cdd755 "usb: ehci: Implement V2P mapping" introduced usage of virt_to_phys() in ehci-hcd. Since there was no implementation of virt_to_phys() for ARC compilation of the ehci-generic driver failed. This change adds virt_to_phys() stub for ARC so now USB driver for AXS101 board could be built again.
