ttm_bo_access() returns the size on success, account for that otherwise
the caller incorrectly thinks this is an error in
intel_atomic_prepare_plane_clear_colors().

- Make sure we check for the partial copy case. Also since this api is
easy to get wrong, wrap the whole thing in a new helper to hide the
details and then convert the existing users over.

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 reStructuredText 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.
