--------------------------------

[ Upstream commit e7417421d89358da071fd2930f91e67c7128fbff ]

If the firmware gives bad input, that's nothing to do with
    the driver's stack at this point etc., so the WARN_ON()
    doesn't add any value. Additionally, this is one of the
    top syzbot reports now. Just print a message, and as an
    added bonus, print the sizes too.
