Subject: [RFC/PATCH] staging: olpc_dcon: Use WARN_ON instead of BUG_ON

This is with respect to a CHECK: "Avoid crashing the
kernel. Use WARN_ON instead of BUG_ON". But I maybe wrong here. Is a
kernel crash desired if olpc_board_at_least(olpc_board(0xc2)) fails,
will there be inconsistent results if execution continues?
