From 2fc82c2de604deabb86b0558be0a301bb2209a19 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Fri, 10 Jan 2014 19:36:42 +0100 Subject: usb: core: allow a reference device for new_id Often, usb drivers need some driver_info to get a device to work. To have access to driver_info when using new_id, allow to pass a reference vendor:product tuple from which new_id will inherit driver_info.
