Subject: vulkan: Add EXT_direct_mode_display [v2]
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=352d320a07458eb05e4929fdc1e0d1dbe1b07dda;p=mesa.git

vulkan: Add EXT_direct_mode_display [v2]

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@intel.com>
