commit e65af5403e462ccd7dff6a045a886c64da598c2e upstream.
usbnet provides some helper functions that are also used in
the context of reset() operations. During a reset the other
drivers on a device are unable to operate. As that can be block
drivers, a driver for another interface cannot use paging
in its memory allocations without risking a deadlock.
Use GFP_NOIO in the helpers.

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.
