commit 0d2ada05227881f3d0722ca2364e3f7a860a301f upstream.
If the current USB request was aborted, the spi thread would not respond
to any further requests. This is because the "curr_urb" pointer would
not become NULL, so no further requests would be taken off the queue.
The solution here is to set the "urb_done" flag, as this will cause the
correct handling of the URB. Also clear interrupts that should only be
expected if an URB is in progress.
Fixes: 2d53139f31 ("Add support for using a MAX3421E chip as a host driver.")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
