Johan Hovold cec7549617 Input: keyspan-remote - fix control-message timeouts
commit ba9a103f40fc4a3ec7558ec9b0b97d4f92034249 upstream.

The driver was issuing synchronous uninterruptible control requests
without using a timeout. This could lead to the driver hanging on probe
due to a malfunctioning (or malicious) device until the device is
physically disconnected. While sleeping in probe the driver prevents
other devices connected to the same hub from being added to (or removed
from) the bus.

The USB upper limit of five seconds per request should be more than
enough.

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.
