The kalmia driver should validate that the device it is probing has the
proper number and types of USB endpoints it is expecting before it binds
to it.  If a malicious device were to not have the same urbs the driver
will crash later on when it blindly accesses these endpoints.

Hi Greg,

As a fix I think this warrants a fixes tag.
As this seems problem to go back to when this driver was added,
perhaps this one:

Fixes: d40261236e8e ("net/usb: Add Samsung Kalmia driver for Samsung GT-B3730")

Regardless, this looks good to me.

Thanks for the review for this and the kaweth patch.  And yes, I should
have put a fixes tag there, but for stuff that's always been around,
that's not really a big deal.
