Yes.  And it works, which is why the compiling and testing doesn't
catch it :P  I'll change it.

OK.

No.  ata_device_add returns nonzero on success; so say the docs. 
Since the return value is not checked here, and whether on success or
failure all of the data structures allocated in that method stick
around, I assumed that something was in the works for this.  I'll
change this to kfree(hp) on returning 0.  Please advise if I should do
something else.

OK.
