[PATCH 2/7] HID: hiddev: use hid_hw_power instead of usbhid_get/put_power

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Instead of calling into usbhid code directly, let's use the standard
accessors for the transport HID drivers.

This also allows us to remove usbhid_get/put_power(), leaving only
usbhid_power().
