plane_state->uapi.crtc is not what we want to be looking at.
If bigjoiner is used hw.crtc is what tells us what crtc the plane
is supposedly using.
Not an actual problem on current hardware as the only FBC capable
pipe (A) can't be a bigjoiner slave and thus uapi.crtc==hw.crtc
always here. But when we get more FBC instances this will become
actually important.

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.
