Subject: [PATCH v1 02/21] PCI/MSI: Remove useless bus->msi assignment
Date: Fri, 5 Sep 2014 18:09:47 +0800	[thread overview]
Message-ID: <1409911806-10519-3-git-send-email-wangyijing@huawei.com> (raw)
In-Reply-To: <1409911806-10519-1-git-send-email-wangyijing@huawei.com>

Currently, PCI drivers will initialize bus->msi in
pcibios_add_bus(). pcibios_add_bus() will be called
in every pci bus initialization. So the bus->msi
assignment in pci_alloc_child_bus() is useless.
