[BUG] common/usb.c: taking address of packed member of ‘struct usb_device_descriptor’ may result in an unaligned pointer value

Hello Marek, with powerpc64-linux-gnu-gcc, version 9.2.1, big endian I see the errors below. struct usb_device_descriptor is naturally packed. Why do we need the packed attribute in include/linux/usb/ch9.h? If it is needed, we should replace le16_to_cpus() by an alignment friendly
