[PATCH] USB: <linux/usb_gadget.h> doc updates
As more people have been using this API, the need for some clarifications has (no surprise!) came up. Most significant is the halt processing, needed to make Alan's "File Storage Gadget" (mass storage class, talks to usb-storage and Windows) handle fault cases cleanly. Gadget drivers can't halt IN endpoints until the FIFO is emptied by the host ... virtually no hardware tries to sequence the DATA and STALL packets by itself.
