Ville Syrjälä 854efdc7ef drm/i915: Introduce intel_dumb_fb_max_stride()
Wrap intel_plane_fb_max_stride() in intel_dumb_fb_max_stride()
for the purposes of dumb fb creation. I want to change
intel_plane_fb_max_stride() to take a 'struct drm_format_info'
instead of the 'u32 pixel_format' so we need an excplicit format
info lookup in the dumb fb path and I don't really want to have
that in i915_gem_dumb_create() directly.

This makes intel_plane_fb_max_stride() internal to the display
code again, and thus we can pass in struct intel_display instead
of struct drm_device.

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.
