From: Lu Baolu baolu.lu@linux.intel.com Date: Tue, 7 Nov 2017 10:28:15 +0800 Subject: USB: early: Use new USB product ID and strings for DbC device
From: Lu Baolu baolu.lu@linux.intel.com
commit c67678ec78eff9cf1e7e997fe6c37c9fcccfc5b8 upstream.
The DbC register set defines an interface for system software to specify the vendor id and product id for the debug device. These two values will be presented by the debug device in its device descriptor idVendor and idProduct fields.
The current used product ID is a place holder. We now have a valid one. The description strings are changed accordingly.
This patch should be back-ported to kernels as old as v4.12, that contain the commit aeb9dd1de98c ("usb/early: Add driver for xhci debug capability").
