We didn't take a copy of the runtime_info? Ww should have done at least,
that's even more volatile than device_info.

It'll do for now, but would be nicer if RUNTIME_INFO(i915) wasn't baked
so hard into the subplatform :)

Could do yeah.

+{

+               __platform_mask_index(i915, INTEL_INFO(i915)->platform);

+                       mask |= BIT(INTEL_SUBPLATFORM_PINEVIEW_G);
+               else if (devid == 0xa011)
+                       mask |= BIT(INTEL_SUBPLATFORM_PINEVIEW_M);

I take it, leaving is-mobile conversion for the display gurus?

Ville said it will be hard so I did not even look. :) Okay, it doesn't seem that hard.. but definitely wouldn't stuff it into this patch.
