ata: libata-eh: Increase STANDBY IMMEDIATE timeout
Correct a previous change (see Fixes) which reduced the standby timeout
from 30 to 5 seconds. Increase it to 15 seconds.
I was troubleshooting an error spotted during system suspend:
[ 1217.152867] ata1.00: Entering standby power mode
[ 1222.322948] ata1.00: qc timeout after 5000 msecs (cmd 0xe0)
[ 1222.324010] ata1.00: STANDBY IMMEDIATE failed (err_mask=0x4)
This drive is a Samsung 870 EVO SSD in good SMART standing, and I wasn't
aware of any reason it should be taking so long to standby. The issue is
intermittent, but I observed it sometimes taking 7 seconds to manually
standby. I assume this was interruption of background maintenance after
a power outage.
As a desktop user, I would prefer to wait the extra 2 seconds at suspend
to let the drive finish its business rather than drop the rails from
under it.
The change from 30 to 5 seconds was implicit when switching suspend
from START STOP UNIT to an internal command with no timeout table entry.
No reason was stated for the change.
