Mika Kahola a4ed5f3ab0 drm/i915/display: Drop crtc_state from C10/C20 pll programming
For PLL programming for C10 and C20 we don't need to
carry crtc_state but instead use only necessary parts
of the crtc_state i.e. pll_state.

This change is needed to PTL wa 14023648281 where we would
need to otherwise pass an artificial crtc_state with majority
of the struct members initialized as NULL.

v2: Use err instead of val for error handling (Imre)
    Unify parameter order (Imre)
v3: Fix misplaced port_clock, and is_dp in
    intel_c20_pll_program() call (Imre)

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.
