If we have to force the hardware to go through a full modeset due to eg. cdclk reprogramming, we need to preserve crtc_state->inherited for all crtcs that have not otherwise gone through the whole compute_config() stuff after connectors have been detected. Otherwise eg. cdclk induced modeset glk_force_audio_cdclk() will clear the inherited flag, and thus the first real commit coming from userspace later on will not be forced through the full .compute_config() path and so eg. audio state may not get properly recomputed. But instead of adding all kinds of ad-hoc crtc_state->inherited preservation hacks all over, let's change things so that we only clear it for the crtcs directly included in userspace/client initiated commits. Should be far less fragile since now we just need to remember to flag the internal commits, and not worry about where new crtcs might get pulled in.

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.
