Subject: [PATCH v4 2/9] PCI/MSI/s390: Remove superfluous check of MSI type
Date: Mon, 16 Dec 2013 09:34:55 +0100	[thread overview]
Message-ID: <f317583c5dda2b440ac2906b2cd04c97cae5ed1b.1387140921.git.agordeev@redhat.com> (raw)
In-Reply-To: <cover.1387140921.git.agordeev@redhat.com>

arch_setup_msi_irqs() hook can only be called from the generic
MSI code which ensures correct MSI type parameter.

Signed-off-by: Alexander Gordeev <agordeev@redhat.com>
