Sean Young 2f2f3c6a4d media: Revert "media: dvb-usb: Fix unexpected infinite loop in dvb_usb_read_remote_control()"
commit 0c84bde4f37ba27d50e4c70ecacd33fe4a57030d upstream.

This reverts commit 2052138b7da52ad5ccaf74f736d00f39a1c9198c.

This breaks the TeVii s480 dual DVB-S2 S660. The device has a bulk in
endpoint but no corresponding out endpoint, so the device does not pass
the "has both receive and send bulk endpoint" test.

Seemingly this device does not use dvb_usb_generic_rw() so I have tried
removing the generic_bulk_ctrl_endpoint entry, but this resulted in
different problems.

As we have no explanation yet, revert.

README

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.
