    Date
    Commit e78355b577c4b ("usb: gadget: udc: atmel: Don't use DT to
    configure end point") pulled out all functionality dealing with 'pp'.

    Fixes the following W=1 kernel build warning(s):

    drivers/usb/gadget/udc/atmel_usba_udc.c: In function ‘atmel_udc_of_init’:
    drivers/usb/gadget/udc/atmel_usba_udc.c:2106:22: warning: variable ‘pp’ set but not used [-Wunused-but-set-variable]
