written dTD's next dtd pointer need to be updated once CPU writes it, or this request may not be handled by controller, then host will get NAK from device forever. This problem occurs when there is a request is handling, we need to add a new request to dTD list, if this new request is added before the current one is finished, the new request is intended to added as next dtd pointer at current dTD, but without wmb(), the dTD's next dtd pointer may not be updated when the controller reads it. In that case, the controller will still get Terminate Bit is 1 at dTD's next dtd pointer, that means there is no next request, then this new request is missed by controller.

2012-05-04usb: gadget: composite: prevent a memory leak when configuration bind failsYongsul Oh
In some USB composite gadget drivers, the configuration's bind function called by the usb_add_config() calls multiple bind config functions. (for example cdc2 configuration bind function in the cdc_do_config() of the cdc2.c has two functionality bind config functions. - the ecm_bind_config() & the acm_bind_config()) In each functionality bind config function, new instance is allocated and finally added by the usb_add_function(). So if an error occurred during the second functionality bind config (for example an error occurred at the acm_bind_config() after succeeding of the ecm_bind_function()), the instance created by the acm_bind_config() cannot be freed creating a memory leak. This patch fixes this issue. Signed-off-by: Yongsul Oh <yongsul96.oh@samsung.com> Acked-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2012-05-04usb: gadget: dummy_hcd: allow to free requests on disabled endpointsSebastian Andrzej Siewior
ep->desc is set to NULL on endpoint disable. That means once an endpoint is disabled it is not possible to free requests. In my target gadget I first disable endpoints to make sure I have no requests on the fly and then free frequests. On dummy I am leaking memory here. Since I can't imagine a reason why it should be a bad thing, lets allow to free requests on disabled endpoints. On removal of composite the ep0 request is removed so lets allow that here as well.

2012-05-04igb, ixgbe: netdev_tx_reset_queue incorrectly called from tx init pathJohn Fastabend
igb and ixgbe incorrectly call netdev_tx_reset_queue() from i{gb|xgbe}_clean_tx_ring() this sort of works in most cases except when the number of real tx queues changes. When the number of real tx queues changes netdev_tx_reset_queue() only gets called on the new number of queues so when we reduce the number of queues we risk triggering the watchdog timer and repeated device resets. So this is not only a cosmetic issue but causes real bugs. For example enabling/disabling DCB or FCoE in ixgbe will trigger this.
