During console setup imx_uart_console_setup() enables clocks, but they are never disabled when the console is unregistered, this leads to clk_prepare_enable() being called multiple times without a matching clk_disable_unprepare() in case of console unregister. Ensure that clock enable/disable are balanced adding clk_disable_unprepare() in the console exit callback.

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.
