This patch simplifying the handling of modeset locks and atomic state for an atomic commit is based on https://lore.kernel.org/all/[email protected]/ adding the helper to i915. I find this approach preferrable than open-coding the corresponding steps (fixed for me an atomic state reset during a DEADLK retry, which I missed in the open-coded version) and also better than the existing DRM_MODESET_LOCK_ALL_BEGIN/END macros for the reasons described in the above original patchset. This change takes the helper into use only for atomic commits during DDI hotplug handling, as a preparation for a follow-up patch adding a similar commit started from the same spot. Other places doing a driver-internal atomic commit is to be converted by a follow-up patchset.

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.
