While the current locking/serialization of the global state suffices for protecting the obj->state access and the actual hardware reprogramming, we do have a problem with accessing the old/new states during nonblocking commits. The state computation and swap will be protected by the crtc locks, but the commit_tails can finish out of order, thus also causing the atomic states to be cleaned up out of order. This would mean the commit that started first but finished last has had its new state freed as the no-longer-needed old state by the other commit. To fix this let's just refcount the states. obj->state amounts to one reference, and the intel_atomic_state holds extra references to both its new and old global obj states. Fixes: |

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.
