Subject: sparse: define dummy BUILD_BUG_ON definition for sparse
From: KOSAKI Motohiro <kosaki.motohiro@xxxxxxxxxxxxxx>
BUILD_BUG_ON() causes a syntax error to detect coding errors. So it
causes sparse to detect an error too. This reduces sparse's usefulness.
This patch makes a dummy BUILD_BUG_ON() definition for sparse.
