Aside of that BUG_ON() should only be used as last resort, which is clearly not the case here. A broad variety of checks in the invoked functions (always enabled or debug option dependent) cover these conditions already, so the BUG_ON()'s do not really provide additional value. Just remove them. Signed-off-by: Sebastian Andrzej Siewior Cc: Kalle Valo Cc: "David S.
