Mathias Nyman a400efe455 xhci: zero usb device slot_id member when disabling and freeing a xhci slot
set udev->slot_id to zero when disabling and freeing the xhci slot.
Prevents usb core from calling xhci with a stale slot id.

xHC controller may be reset during resume to recover from some error.
All slots are unusable as they are disabled and freed.
xhci driver starts slot enumeration again from 1 in the order they are
enabled. In the worst case a stale udev->slot_id for one device matches
a newly enabled slot_id for a different device, causing us to
perform a action on the wrong device.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
