In the error handling path, the clk_prepare_enable() function
call should be balanced by a corresponding 'clk_disable_unprepare()'
call , as already done in the remove function.
clk_disable_unprepare calls clk_disable() and clk_unprepare().
They will use IS_ERR_OR_NULL to check the argument.
Fixes: ac05fba39c ("rtc: gemini: Add optional clock handling")

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.
