Hi Greg: The cause is that these two routines are replaced with two new routines: acpi_dev_pm_add_dependent() and acpi_dev_pm_remove_dependent() in the linux-next branch of linux-pm tree. So this error doesn't take place in the usb-next tree. One solution I can think of is that bother you to revert the patch and I will send new patch with new routines after 3.9 merge window. This will not affect other functions. Does this make sense? Sorry again.
