ata_do_reset() ?

The loop is inside ata_eh_reset(), so it sounds a bit weird to exit
the loop early if the function itself returns -ENODEV.


I guess you could also write it like:
Prevent unnecessary reset retries by exiting the loop early when
a callee in ata_eh_reset() returns -ENODEV.


Kind regards,
