Ville Syrjälä 0646d0dd66 drm/i915: Eliminate one more frequent drm_format_info()
Another (somewhat expensive) drm_format_info() call has
appeared in intel_plane_can_async_flip(). That one may get
called several times per commit so we need to get rid of
it.

Fortunately most callers already have the framebuffer at
hand, so we can just grab the format info from there.
The one exception is intel_plane_format_mod_supported_async()
where we have to do the lookup. But that only gets called
(a bunch of times) during driver init to build the
IN_FORMATS_ASYNC blob, and afterwards there is no runtime
cost.

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.
