[ Upstream commit 25b4614843bcc56ba150f7c99905125a019e656c ]
The driver isn't supposed to consult crtc_state->active/active_check for
resource allocation. Instead all resources should be allocated if
crtc_state->enabled is set. Stop consulting active / active_changed in
order to determine whether the hardware resources should be
(re)allocated.

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.
