Test whether the given link is offline
bool ata_link_offline(struct ata_link * link);
link
ATA link to test
Test whether link is offline. This is identical to ata_phys_link_offline when there's no slave link. When there's a slave link, this function should only be called on the master link and will return true if both M/S links are offline.
