* usb: gadget: r8a66597: fix unused-but-set-variable warningsMichal Nazarewicz2016-06-21
| | | | | | | | | | | | | | | | | | | This patch fixes the following (W=1) warnings: drivers/usb/gadget/udc/r8a66597-udc.c: In function ‘r8a66597_irq’: drivers/usb/gadget/udc/r8a66597-udc.c:1468:15: warning: variable ‘nrdyenb’ set but not used [-Wunused-but-set-variable] u16 brdyenb, nrdyenb, bempenb; ^ drivers/usb/gadget/udc/r8a66597-udc.c:1467:15: warning: variable ‘nrdysts’ set but not used [-Wunused-but-set-variable] u16 brdysts, nrdysts, bempsts; ^ In doing so, it removes calls to r8a66597_read function which does I/O with the device, but I hope the reads don’t have any side effects that are needed.

* usb: gadget: r8a66597-udc: Deinline pipe_change, save 2176 bytesDenys Vlasenko2016-04-19
| | | | | | | | | | | | | This function compiles to 298 bytes of machine code, has ~10 callsites. This is a USB 2.0 device, USB 2.0 is limited to ~40 MB/s, so should be almost never CPU bound. No need to optimize for speed this agressively.

* usb: gadget: remove incorrect __init/__exit annotationsArnd Bergmann2015-04-27
| | | | | | | | | | | | | | | | | | | | | | | | A recent change introduced a link error for the composite printer gadget driver: `printer_unbind' referenced in section `.ref.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o Evidently the unbind function should not be marked __exit here, because it is called through a callback pointer that is not necessarily discarded, __composite_unbind() is indeed called from the error path of composite_bind(), which can never work for a built-in driver. Looking at the surrounding code, I found the same problem in all other composite gadget drivers in both the bind and unbind functions, as well as the udc platform driver 'remove' functions. Those will break if anyone uses the 'unbind' sysfs attribute to detach a device from a built-in driver. This patch removes the incorrect annotations from all the gadget drivers.

* usb: gadget: remove unnecessary 'driver' argumentFelipe Balbi2014-11-03
| | | | | | | | | | | | | | | | | | | | | | 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.

* usb: gadget: Refactor request completionMichal Sojka2014-09-25
| | | | | | | | | | | | | | Use the recently introduced usb_gadget_giveback_request() in favor of direct invocation of the completion routine. All places in drivers/usb/ matching "[-.]complete(" were replaced with a call to usb_gadget_giveback_request(). This was compile-tested with all ARM drivers enabled and runtime-tested for musb.
