Re: [PATCH net v2] mctp i2c: fix double free of midev on netdev register failure

[Kenny Hsieh]

The double free is from code inspection. 
Sashiko flagged it while reviewing another mctp-i2c patch, and I checked it against the register_netdevice() error paths. 
The late failures need an internal allocation or notifier error, so I haven't hit it on hardware.
