Yeah, that's weird and kind of concerning. I don't think either compiler is 
able to see that the init function return values are always ignored. I had 
to dig into init/main.c to convince myself.

Yeah, so I left the Fixes tag out of the commit anyway, because this isn't 
really a fix that -stable should concern itself with. After the first 
commit it's not even a fix per se, but an improvement in the resolution & 
meaning of error codes or so.

Thanks,
