Ah, wasn't the patch named "[PATCH v1] usb: gadget: pxa27x_udc: fix warning in
non device-tree build" sent October the 29th fixing this issue (in [1]) ?

The recent change bringing device-tree support triggers a warning in a
non device-tree build :
  drivers/usb/gadget/udc/pxa27x_udc.c:2405:28: warning: 'udc_pxa_dt_ids'
  defined but not used [-Wunused-variable]

Fix the warning with a preprocessor condition.
