Pavel Skripkin d30d3397db media: dvb-usb: fix ununit-value in az6027_rc_query
[ Upstream commit afae4ef7d5 ]

Syzbot reported ununit-value bug in az6027_rc_query(). The problem was
in missing state pointer initialization. Since this function does nothing
we can simply initialize state to REMOTE_NO_KEY_PRESSED.

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.
