Martin Kelly ba4eed1bd4 can: mcba_usb: fix device disconnect bug
commit 1cb35a33a2 upstream.

Currently, when you disconnect the device, the driver infinitely
resubmits all URBs, so you see:

Rx URB aborted (-32)

in an infinite loop.

Fix this by catching -EPIPE (what we get in urb->status when the device
disconnects) and not resubmitting.

With this patch, I can plug and unplug many times and the driver
recovers correctly.

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.
