I noticed some weird behavior using DFU gadget on AT91SAM9260 which worked 1 of 10 times. The bug was due to the usb_gadget_poll() being called while the previous call was still in progress : some USB calls may takes a lot of time (ex : DFU erase-then-write), resulting in the poller to be triggered again while still in the poll() function.
This patch adds a poll lock to the AT91 UDC driver.
