Sean Young b2b5126a77 media: ite-cir: IR receiver stop working after receive overflow
commit fdc8817830 upstream.

On an Intel NUC6iSYK, no IR is reported after a receive overflow.

When a receiver overflow occurs, this condition is only cleared by
reading the fifo. Make sure we read anything in the fifo.

Fixes: 28c7afb07c ("media: ite-cir: check for receive overflow")

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.
