After registering the audio component in i915_audio_component_init() the audio driver may call i915_audio_component_get_power() via the component ops. This could program AUD_FREQ_CNTRL with an uninitialized value if the latter function is called before display.audio.freq_cntrl gets initialized. The get_power() function also does a modeset which in the above case happens too early before the initialization step and triggers the "Reject display access from task" error message added by the Fixes: commit below. Fix the above issue by registering the audio component only after the initialization step.

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 reStructuredText 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.
