Maarten Lankhorst 4edd608472 drm/atomic: Make atomic helper track newly assigned planes correctly, v2.
Commit 669c9215afea ("drm/atomic: Make async plane update checks work as
intended, v2.") forced planes to always be tracked, but forgot to
explicitly get the crtc commit from the new crtc when available.

This broke plane commit tracking, and caused kms_atomic_transitions
to randomly fail with -EBUSY.

Changes since v1:
- Prefer new_crtc_state->crtc above old_crtc_state->crtc.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
