Following sparse warnings were reported by kbuild test bot
drivers/usb/misc/lvstest.c:314:28: sparse: incorrect type in assignment (different base types)
drivers/usb/misc/lvstest.c:314:28: expected unsigned short [unsigned] [usertype] portchange
drivers/usb/misc/lvstest.c:314:28: got restricted __le16 [usertype] wPortChange
drivers/usb/misc/lvstest.c:332:40: sparse: restricted __le16 degrades to integer
This patch fixes above warnings.
