Subject: [PATCH] powerpc/PCI hotplug: merge rpaphp_enable_pci_slot()
Date: Fri, 20 Jan 2006 11:04:39 -0800 [thread overview]
Message-ID: <11377838792136@kroah.com> (raw)
In-Reply-To: <1137783879865@kroah.com>
[PATCH] powerpc/PCI hotplug: merge rpaphp_enable_pci_slot()
Remove general baroqueness. The function rpaphp_enable_pci_slot()
has a fairly simple logic structure, once all of the debug printk's
are removed. Its called from only one place, and that place also
has a very simple structure once he printk's are removed. Merge
the two together.
