Subject: [PATCH net-next 01/15] net: orinoco: Remove BUG_ON(in_interrupt/irq())
Date: Tue, 27 Oct 2020 23:54:40 +0100	[thread overview]
Message-ID: <20201027225454.3492351-2-bigeasy@linutronix.de> (raw)
In-Reply-To: <20201027225454.3492351-1-bigeasy@linutronix.de>

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.
