Subject: [PATCH] powerpc/PCI hotplug: merge config_pci_adapter
X-Git-Tag: v2.6.16-rc2~176^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7fec77e4793f307b30846a3d4015d329ffc0b685;p=platform%2Fkernel%2Flinux-exynos.git

[PATCH] powerpc/PCI hotplug: merge config_pci_adapter

Remove general baroqueness.  The function rpaphp_config_pci_adapter()
is really just one line of code, once all the dbg printks are removed.
And its called in only one place. So replace the call by the one line.
