Oliver: It's time to think about converting the USB subsystem over to Rafael's new runtime PM framework. It's highly compatible with the code we already have, except for one thing: The usage counters have to follow a strict get/put model. In other words, we can't allow drivers to access the analog of intf->pm_usage_cnt directly, and we can't support usb_autopm_set_interface(), usb_autopm_enable(), or usb_autopm_disable(). For the most part I think this doesn't matter. Those routines are used in only a few drivers, and it looks like they can be replaced with usb_autopm_get_interface() and usb_autopm_put_interface(). Still, it's worth checking carefully -- the first step of the conversion will be to make those replacements. In particular, do you agree this will be okay for the net/usb/kaweth, net/wimax/i2400m, and media/video/stk-webcam drivers? The only other place these things get used is the hub driver, and I can fix that.
