The usage of in_irq()/in_interrupt() in drivers is phased out and the BUG_ON()'s based on those are not covering all contexts in which these functions cannot be called. 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.
