3.16.47-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Alexey Brodkin <Alexey.Brodkin@xxxxxxxxxxxx> commit 3d6159640da9c9175d1ca42f151fc1a14caded59 upstream. DWC3 driver uses of_usb_get_phy_mode() which is implemented in drivers/usb/phy/of.c and in bare minimal configuration it might not be pulled in kernel binary. In case of ARC or ARM this could be easily reproduced with "allnodefconfig" +CONFIG_USB=m +CONFIG_USB_DWC3=m. On building all ends-up with: ---------------------->8------------------ Kernel: arch/arm/boot/Image is ready Kernel: arch/arm/boot/zImage is ready Building modules, stage 2.
