[Intel-gfx] [PATCH 7/8] drm/i915: allow per-device fbc to work with default settings

[Eugeni Dodonov]

The change which added support for default settings for fbc has not
changed the variable type of i915_enable_fbc from unsigned int to int. So
we were unable to get into the default ('-1') state with the default
settings.
