Two update suggestions were taken into account
from static source code analysis.
Markus Elfring (2):
Delete an error message for a failed memory allocation in at76_submit_rx_urb()
Improve size determinations in at76_usbdfu_download()

Replace the specification of two data types by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
