Currently, we set drm_dp_atomic_payload->time_slots to 0 in order to indicate that we're about to delete a payload in the current atomic state. Since we're going to be dropping all of the legacy code for handling the payload table however, we need to be able to ensure that we still keep track of the current time slot allocations for each payload so we can reuse this info when asking the root MST hub to delete payloads. We'll also be using it to recalculate the start slots of each VC. So, let's keep track of the intent of a payload in drm_dp_atomic_payload by adding ->delete, which we set whenever we're planning on deleting a payload during the current atomic commit.

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.
