+Subject: Fix ohci-ssb with !CONFIG_PM
+X-Git-Tag: linux-2.6.24-rc1~57^2~38
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fralf%2Flinux.git;a=commitdiff_plain;h=4735b37cf434175c2b7b36b3b68f1e60e8ec8527;hp=d773b33972a663cfaf066e966f87922a74088a1e
+
+Fix ohci-ssb with !CONFIG_PM
+
+ohci_bus_{suspend,resume} exists only if we have CONFIG_PM; do the same
+thing as other subdrivers...
