Stanislaw Gruszka 769bfea594 rt2x00usb: mark device removed when get ENOENT usb error 
commit bfa62a52ca upstream.

ENOENT usb error mean "specified interface or endpoint does not exist or
is not enabled". Mark device not present when we encounter this error
similar like we do with ENODEV error.

Otherwise we can have infinite loop in rt2x00usb_work_rxdone(), because
we remove and put again RX entries to the queue infinitely.

We can have similar situation when submit urb will fail all the time
with other error, so we need consider to limit number of entries
processed by rxdone work. But for now, since the patch fixes
reproducible soft lockup issue on single processor systems
and taken ENOENT error meaning, let apply this fix.

Patch adds additional ENOENT check not only in rx kick routine, but
also on other places where we check for ENODEV error.

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.
