From b7945b77cd03094458f3624bc82a27e0d36e75d0 Mon Sep 17 00:00:00 2001 From: Valentina Manea Date: Thu, 23 Jan 2014 23:12:29 +0200 Subject: staging: usbip: convert usbip-host driver to usb_device_driver This driver was previously an interface driver. Since USB/IP exports a whole device, not just an interface, it would make sense to be a device driver. This patch also modifies the way userspace sees and uses a shared device: * the usbip_status file is no longer created for interface 0, but for the whole device (such as /sys/devices/pci0000:00/0000:00:01.2/usb1/1-1/usbip_status). * per interface information, such as interface class or protocol, is no longer sent/received; only device specific information is transmitted. * since the driver was moved one level below in the USB architecture, there is no need to bind/unbind each interface, just the device as a whole.
