[PATCH] USB: gadget driver updates (SETUP api change)
This updates most of the gadget framework to expect SETUP packets use
USB byteorder (matching the annotation in <linux/usb_ch9.h> and usage
in the host side stack):
- definition in <linux/usb_gadget.h>
- gadget drivers: Ethernet/RNDIS, serial/ACM, file_storage, gadgetfs.
- dummy_hcd
It also includes some other similar changes as suggested by "sparse",
which was used to detect byteorder bugs.
