Kai-Heng Feng 9521362753 drm/amdgpu/acp: Make PM domain really work
[ Upstream commit aff890288de2d818e4f83ec40c9315e2d735df07 ]

Devices created by mfd_add_hotplug_devices() don't really increase the
index of its name, so get_mfd_cell_dev() cannot find any device, hence a
NULL dev is passed to pm_genpd_add_device():
[   56.974926] (NULL device *): amdgpu: device acp_audio_dma.0.auto added to pm domain
[   56.974933] (NULL device *): amdgpu: Failed to add dev to genpd

Instead of finding MFD hotplugged device by its name, simply iterate
over the child devices to avoid the issue.

README

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.
