Johan Hovold e02214399e serial: qcom-geni: fix opp vote on shutdown
commit 8ece7b754b upstream.

The operating-performance-point vote needs to be dropped when shutting
down the port to avoid wasting power by keeping resources like power
domains in an unnecessarily high performance state (e.g. when a UART
connected Bluetooth controller is not in use).

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.
