What's confusing me is this reordering of these macros. Was there a
particular reason for doing that?
Outside that it all looks pretty reasonable. Could got a bit further
with passing around dev_priv in some cases, but I guess we can leave
that to future work.
One random idea that did pop into my head was this:
static inline const struct ... *
intel_info(struct drm_i915_private *dev_priv)
{
return &dev_priv->info;
}
#define HAS_WHATEVER(dev_priv) (intel_info(dev_priv)->whatever)
for some extra type safety. Any thoughts?
