->prereset() returns -ENOENT to tell libata that the port is empty and reset sequencing should be stopped. This is not an error condition. Update ata_eh_reset() such that it sets device classes to ATA_DEV_NONE and return success in on -ENOENT. This makes spurious error message go away. Signed-off-by: Tejun Heo <htejun@xxxxxxxxx> --- This should do it and better fits the intention of the return value. Two things to note. 1. I think these ports should be made dummy instead of returning -ENOENT on prereset(). -ENOENT from prereset() was a hack to keep ata_piix's behavior unchanged while converting it to new EH. If no one objcts, I'll convert similar usages to use dummy ports after new init model and drop -ENOENT hack in #upstream. 2. -ENODEV sounds more appropriate. Why have I used -ENOENT. :-)
