[Mesa-dev] [PATCH mesa 4/9] vulkan: Add EXT_direct_mode_display [v2]

[Keith Packard]

Add support for the EXT_direct_mode_display extension. This just
provides the vkReleaseDisplayEXT function.

v2:
	Adopt Jason Ekstrand's coding conventions

	Declare variables at first use, eliminate extra whitespace
	between types and names. Wrap lines to 80 columns.

	Suggested-by: Jason Ekstrand <jason.ekstrand at intel.com>
