[Intel-gfx] [PATCH v4 1/3] drm/i915/gvt: Add gvt_debug in i915_params for GVT-g log classification

[Joonas Lahtinen]

The title should begin with "drm/i915:" not "drm/i915/gvt:".

Let's try to keep the struct ordered.

s/message/code/ for the description in braces, like the drm
counterpart. Or change them to be just "GVT-g core", "GVT-g
scheduling", "GVT-g commands" etc.

One tab indent is enough like mostly used in the file.
