ata_std_prereset: prepare for reset
ata_std_prereset - prepare for reset
int ata_std_prereset(struct ata_link
*link, unsigned long deadline);
- ATA link to be reset
- deadline jiffies for the operation
link is about to be reset. Initialize it. Failure from prereset makes libata abort whole reset sequence and give up that port, so prereset should be best-effort. It does its best to prepare for reset sequence but if things go wrong, it should just whine, not fail.
