For consistency clear the icl_port_dplls from the new crtc state, when releasing the DPLLs from the old crtc state. Leaving them set could result in releasing the same PLLs multiple times from the same CRTC state incorrectly (if the same CRTC was first used for a TypeC port then for a combo PHY port). Leaving the stale pointers behind happens not to cause a problem atm (since the incorrect releasing will be a NOP), but we need to fix that for consistency.

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.
