As a matter of fact, we didn't, but I made a typo on the first one:

-	for (reg = lmb.lmb_type.regions;                                   \
+	for (region = lmb.lmb_type.regions;                                \
		region < (lmb.lmb_type.regions + lmb.lmb_type.cnt);        \
	        region++)

I'll fix that in my series.

Cheers,
Ben.
