Subject: [PATCH 3/3] x86/irq: slightly improve do_IRQ
Date: Sun, 4 Aug 2019 10:22:24 +0200 [thread overview]
Message-ID: <b803cef2-8959-985b-9d71-4abec1417600@gmail.com> (raw)
In-Reply-To: <c9b51ac3-b1d6-89a6-e323-4600af22d9de@gmail.com>
It's simpler and more intuitive to directly check for VECTOR_UNUSED.
