Hi Greg,

After merging the usb tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/usb/core/usb-acpi.c: In function 'usb_acpi_register_power_resources':
drivers/usb/core/usb-acpi.c:226:2: error: implicit declaration of function 'acpi_power_resource_register_device' [-Werror=implicit-function-declaration]
drivers/usb/core/usb-acpi.c: In function 'usb_acpi_unregister_power_resources':
drivers/usb/core/usb-acpi.c:234:3: error: implicit declaration of function 'acpi_power_resource_unregister_device' [-Werror=implicit-function-declaration]

Caused by commit 88bb965ed711 ("usb: Register usb port's acpi power
resources").

I have used the usb tree from next-20130125 for today.

Lan, please send me a patch to resolve this issue.
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.


Stephen, sorry for the breakage.

thanks,

greg k-h
