[PATCH 01/29] pci: Decouple quirks.c from i915_reg.h

[PATCH 01/29] pci: Decouple quirks.c from i915_reg.h

[ville.syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

i915 register defines are going to become type safe, so going forward
the register defines can't be used as straight numbers. Since quirks.c
needs just a few extra register defines from i915_reg.h, decouple the
two by defining the required registers locally in quirks.c. This was
already done for a few other igpu related registers.

Considering this is in a mixed set of quirks, perhaps now would be a
good time to give them an I915_^W IGD_ prefix as well?

But as far as the simple replacement goes,

I haven't seen the rest of this series, but this patch is OK by me,
and I assume you'll merge this along with the whole series.  Please
adjust the subject line to be:

  PCI: Decouple quirks.c from i915_reg.h
