commit ccfa3131d4a0347988e73638edea5c8281b6d2c7 upstream.
Current implementation of fsl_edma3_attach_pd() does not provide a
cleanup path, resulting in a memory leak. For example,
dev_pm_domain_detach() is not called after dev_pm_domain_attach_by_id(),
and the device link created with the DL_FLAG_STATELESS is not released
explicitly.
Therefore, provide a cleanup function fsl_edma3_detach_pd() and call it
upon failure. Also add a devm_add_action_or_reset() call with this
function after a successful fsl_edma3_attach_pd().

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.
