From: Bobby Powers <bobbypowers@xxxxxxxxx>
Subject: headers_check: recursively search for linux/types.h inclusion

headers_check.pl currently emits some spurious warnings, especially for
the drm headers, about using __[us]{8,16,32,64} types without including
linux/types.h.  Recursively search for types.h inclusion, avoiding
circular references.
