Gcc report build warning as follows: drivers/usb/gadget/udc/atmel_usba_udc.c:2106:22: warning: variable pp set but not used [-Wunused-but-set-variable] 2106 | struct device_node *pp; | ^~ After commit e78355b577c4 ("usb: gadget: udc: atmel: Don't use DT to configure end point"), variable 'pp' is never used, so removing it to avoid warning.
