--------------------------------

[ Upstream commit b46ba47d7bb461a0969317be1f2e165c0571d6c5 ]

There's at least one drive (MaxDigitalData OOS14000G) such that if it
receives a large amount of I/O while entering an idle power state will
first exit idle before responding, including causing SMART temperature
requests to be delayed.

This causes the drivetemp request to exceed its timeout of 1 second.
