I was just compiling -rc7, and hit a bit of a roadblock in drivers/usb.
CC drivers/usb/host/ohci-pci.o
drivers/usb/host/ohci-pci.c: In function 'ohci_pci_init':
drivers/usb/host/ohci-pci.c:309:35: error: 'ohci_suspend' undeclared (first use in this function)
ohci_pci_hc_driver.pci_suspend = ohci_suspend;
^
drivers/usb/host/ohci-pci.c:309:35: note: each undeclared identifier is reported only once for each function it appears in
drivers/usb/host/ohci-pci.c:310:34: error: 'ohci_resume' undeclared (first use in this function)
ohci_pci_hc_driver.pci_resume = ohci_resume;
^
make[3]: *** [drivers/usb/host/ohci-pci.o] Error 1
make[2]: *** [drivers/usb/host] Error 2
make[1]: *** [drivers/usb] Error 2
make: *** [drivers] Error 2
This appears to be related to 9a11899c5e699a8d2551692dfcd4372e39dcbdf6,
which added references to ohci_suspend and ohci_resume that didn't have
the same CONFIG_PM wrapper as their declarations in ohci.h.
(FWIW, Documentation/SubmitChecklist step 26 warns about this.)
The following is the obvious fix, but I don't know if it's the right one...
diff --git a/drivers/usb/host/ohci-pci.c b/drivers/usb/host/ohci-pci.c
