[PATCH] usb suspend updates (interface suspend)
This is the first of a few installments of PM API updates to match the
recent switch to "pm_message_t". This installment primarily affects
USB device drivers (for USB interfaces), and it changes the handful of
drivers which currently implement suspend methods:
- <linux/usb.h> and usbcore, signature change
- Some drivers only changed the signature, net effect this just
shuts up "sparse -Wbitwise":
* hid-core
* stir4200
- Two network drivers did that, and also grew slightly more
featureful suspend code ... they now properly shut down
their activities. (As should stir4200...)
* pegasus
* usbnet
Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks
to me like it's missing a request to turn it on, vs just configuring it.
The ASIX code in usbnet also has WOL hooks that are ready to use; untested.
