      usb:composite:fix Provide function data when addressing device with only one interface · f7b4162e
      Lukasz Majewski authored
      This commit fixes problems with some non-standard requests send with
      device address instead of interface address (bmRequestType.Receipent field).
      This happens with dfu-util (debian version: 0.5), which address non standard
      requests (like w_value=0x21 and bRequest=GET_DESCRIPTOR) to device.
      Without this fix, the above request is STALLED, and hence causes dfu-util
      to assume some standard configuration (packet size = 1024B instead of 4096B)
      In turn it displays following errors:
      Error obtaining DFU functional descriptor
      Warning: Assuming DFU version 1.0
      Warning: Transfer size can not be detected
      Warning: Trying default transfer size 1024
      This fix allows passing non-standard request to function setup code, where
      it shall be handled.
      Tested at: 	Trats (exynos4210)
      Tested with:DFU and UMS gadgets
