[PATCH 4.4 093/188] scsi: core: Retry I/O for Notify (Enable Spinup) Required error

From: Quat Le <redacted>

commit 104739aca4488909175e9e31d5cd7d75b82a2046 upstream.

If the device is power-cycled, it takes time for the initiator to transmit
the periodic NOTIFY (ENABLE SPINUP) SAS primitive, and for the device to
respond to the primitive to become ACTIVE. Retry the I/O request to allow
the device time to become ACTIVE.
