Subject: [PATCH RFC 2/6] drm/vkms: Extract vkms_writeback header

> The vkms writeback functions are defined in a different .c, so
> make the same thing for the function declaration in the headers and create
> vkms_writeback.h.

The style for guards used in the other files is:

#ifndef _VKMS_WRITEBACK_H_
#define _VKMS_WRITEBACK_H_

And here a /* */ comment is used:
