Subject: [PATCH 8/8] ARM: PCI: remove per-pci_hw list of buses
Date: Thu, 26 Apr 2012 11:19:17 +0100	[thread overview]
Message-ID: <E1SNLnB-00081I-Sl@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20120426101626.GE24211@n2100.arm.linux.org.uk>

No one uses the per-hw list of buses, so get rid of this.  Instead,
build the list locally.
