Subject: PCI: make isa_bridge Alpha-only
X-Git-Tag: v2.6.21-rc2~42^2~8^2~14
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=8255cf35d503db7c1b26ae53b6b7f23ada82316f;p=linux-2.6-omap-h63xx.git

PCI: make isa_bridge Alpha-only

Since isa_bridge is neither assigned any value !NULL nor used on !Alpha,
there's no reason for providing it.
