ldma_clk_disable() calls both:
clk_disable_unprepare(d->core_clk);
reset_control_assert(d->rst);
So, should devm_reset_control_get_optional() fail, core_clk should not
be prepare_enable'd before it, otherwise it will never be
disable_unprepare'd.
Reorder the code to handle the error handling path as expected.

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.
