* usb: gadget: fix unused-but-set-variale warningsMichal Nazarewicz2016-06-211-5/+0
| | | | | | | | | | | Those are enabled with W=1 make option. The patch leaves of some type-limits warnings which are caused by generic macros used in a way where they produce always-false conditions.

* usb: gadget: dummy_hcd: replace timeval with timespec64WEN Pingbo2015-09-271-3/+3
| | | | | | | | | | | The millisecond of the last second will be normal if tv_sec is overflowed. But for y2038 consistency and demonstration purpose, and avoiding further risks, we need to remove 'timeval' in this driver, to avoid similair problems.

* usb: gadget: dummy_hcd: in transfer(), return data sent, not limitIgor Kotrasinski2015-09-211-2/+4
| | | | | | | | | | | | | | | dummy_timer uses transfer() to update transfer limit. However, limit passed to dummy_timer changes depending on transfer type, so the actual limit is overwritten. This can cause unpredictably slow / fast bulk transfers when coupled with control / interrupt transfers. Fix by returning actual amount of data sent in transfer() and substracting from total.

* usb: gadget: dummy_hcd: fix rescan logic for transferIgor Kotrasinski2015-09-211-5/+8
| | | | | | | | | | | | transfer() schedules a rescan for transfers larger than maxpacket, which is wrong for transfers that are multiples of maxpacket. Rewrite to fix and clarify packet multiple / remainder transfer logic. Signed-off-by: Igor Kotrasinski <i.kotrasinsk@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

* usb: gadget: dummy_hcd: emulate sending zlp in packet logicIgor Kotrasinski2015-09-211-8/+17
| | | | | | | | | | | | | | | | | | currently, when a zlp flag is set and an urb/usb_request buffer is filled without a short packet, transfer() leaves its status at -EINPROGRESS and does not rescan for short packet. In a scenario where ep.maxpacket bytes are copied, URB_ZERO_PACKET is set, urb buffer is filled and usb_request buffer is not, transfer() returns with an urb with -EINPROGRESS status, which dummy_hcd treats as incomplete transfer. Check for zlp and rescan appropriately. Signed-off-by: Igor Kotrasinski <i.kotrasinsk@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

* | usb: gadget: remove unnecessary 'driver' argumentFelipe Balbi2014-11-031-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | now that no UDC driver relies on the extra 'driver' argument to ->udc_stop(), we can safely remove it. This commit is based on previous work by Robert Baldyga <r.baldyga@samsung.com> which can be found at [1]; however that patch turned out to have a high probability of regressing many UDC drivers because of a blind search & replace s/driver/$udc->driver/ which caused the 'driver' argument to stop_activity() to be a valid non-NULL pointer when it should be NULL, thus causing UDCs to mistakenly call gadget driver's ->disconnect() callback.
