Ville Syrjälä 4018169704 drm/i915: Read FORCEWAKE registers with I915_READ_FW() ... Change FORCEWAKE & co. reads for the error state to use I915_READ_FW(). Reading a FORCEWAKE register using a function that can frob forcewake just seems wrong. There is a check to skip grabbing the forcewake for accessing FORCEWAKE in intel_uncore.c, but there's no such check for FORCEWAKE_MT. So no idea what is currently happening with FORCEWAKE_MT reads. FORCEWAKE_VLV is fortunately outside the forcewake range anyway, so no actual issue with that one. So let's just make the rule that you can't access FORCEWAKE registers with the normal I915_READ() stuff, and we can drop the extra FORCEWAKE check from NEEDS_FORCEWAKE(). While at it use NEEDS_FORCEWAKE() on BDW, where it was skipped for whatever bikeshed reason that I've already forgotten.
