Yes. It's assumes only one device is plugged in.

So you don't make it a block device which is even simpler. Now
get_sb_bdev() will fail before attempting to read the superblock. In
iriverfs, we only need to check for USB_DEVICE_MAJOR and then look up
struct usb_device to make sure we're allowed to mount.
