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.
