commit 8e74475b0e0a (usb: dwc3: gadget: use udc-core's reset notifier) added support for the new UDC core's reset notifier to dwc3 but while at it, it removed a spin_lock() from dwc3_reset_gadget() which might cause an unbalanced spin_unlock() further down the line Fixes: 8e74475b0e0a (usb: dwc3: gadget: use udc-core's reset notifier) Cc: <stable@vger.kernel.org> # v3.19 Signed-off-by: Felipe Balbi <balbi@ti.com>

2015-01-27usb: isp1760: Fix USB disabled checkLaurent Pinchart
The isp1760 driver registration function returns an error if USB is disabled. This made sense when the driver only supported host controllers, but now that it supports peripheral controllers host support isn't mandatory anymore. Fix this by returning an error only when both the HCD and UDC functions are disabled, either through the kernel configuration or at runtime.

2015-01-27usb: isp1760: Remove duplicate usb_disabled() checkLaurent Pinchart
Both isp1760_register() and isp1761_pci_probe() check whether USB is disabled by calling usb_disabled(), and bail out with an error if it is. One check is enough, remove the PCI-specific check.

2015-01-27usb: isp1760: Initialize the bus interface in core codeLaurent Pinchart

2015-01-27usb: isp1760: Reorganize header filesLaurent Pinchart
The isp1760-rhcd.h header contains PTD constants and structures only useful for the HCD implementation. It also contains register definitions that will be needed by common code when implementing support for the ISP1761 device controller, but doesn't contain the isp1760_hcd structure definition that will also be used by common code. Move definitions to the right location and create an isp1760-regs.h to store register definitions. No change other than moving definitions and modifying indentation is performed.

2015-01-27usb: gadget: ffs: add eventfd notification about ffs eventsRobert Baldyga
Add eventfd which notifies userspace about ep0 events and AIO completion events. It simplifies using of FunctionFS with event loop, because now we need to poll on single file (instead of polling on ep0 and eventfd's supplied to AIO layer). FunctionFS eventfd is not triggered if another eventfd is supplied to AIO layer (in AIO request). It can be useful, for example, when we want to handle AIO transations for chosen endpoint in separate thread.
