From 8725fcd99a3084a7a15a6e70882bfa3fe7925f52 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Mon, 19 Aug 2019 21:36:39 +0200 Subject: [PATCH] x86/irq: Check for VECTOR_UNUSED directly It's simpler and more intuitive to directly check for VECTOR_UNUSED than checking whether the other error codes are not set.
