Make sure that the CRTC state is reset correctly, as expected after disabling the CRTC. In particular this change will: - Zero all the CSC blob pointers after intel_crtc_free_hw_state() has freed them. - Zero the shared DPLL and port PLL pointers and clear the corresponding CRTC reference flag in the PLL state. - Reset all the transcoder and pipe fields. v2: - Reset fully the CRTC state. (Ville) - Clear pipe active flags in the DPLL state. v3: - Clear only the CRTC reference flag and add a helper for this. (Ville) v4: - Rebased on previous patch, adding intel_unreference_shared_dpll_crtc() separately.

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.
