Subject: [PATCH 14/14] powerpc/pci: Don't try to allocate resources that will be reassigned
Date: Fri, 8 Jul 2016 16:37:18 +1000 [thread overview]
Message-ID: <1467959838-6900-14-git-send-email-benh@kernel.crashing.org> (raw)
In-Reply-To: <1467959838-6900-1-git-send-email-benh@kernel.crashing.org>
When we know we will reassign all resources, trying (and failing)
to allocate them initially is fairly pointless and leads to a lot
of scary messages in the kernel log
