[PATCH v2 1/6] drm/i915: add i915_driver_modeset_remove()

[Jani Nikula]

For completeness, add counterpart to i915_driver_modeset_probe() and
remove the asymmetry in the probe/remove parts. No functional changes.

[PATCH v2 2/6] drm/i915: pass i915 to i915_driver_modeset_probe()

[Jani Nikula]

In general, prefer struct drm_i915_private * over struct drm_device *
when either will do. Rename the local variable to i915. No functional
changes.
