[ Upstream commit 7ab6512e7942889c0962588355cb92424a690be6 ]
When factoring out __vc4_hvs_stop_channel, the logic got inverted from
if (condition)
// stop channel
to
if (condition)
goto out
//stop channel
out:
and also changed the exact register writes used to stop the channel.
Correct the logic so that the channel is actually stopped, and revert
to the original register writes.

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.
