Should this be 'return ret;' (the _start has failed, so why stop?)
Hm, yes.

Should this be 'fail_and_stop' (the _open has failed, so why close?)
Also yes... I based this part on the nzxt-kraken2 driver in the tree,
perhaps that should be investigated as well. The aquacomputer_d5next driver
seems to be doing it correctly.
Done, patch sent.
