scsi: aacraid: Allow reset_host sysfs var to recover Panicked Fw
It is possible to restart the controller via the use of the reset_host sysfs variable. This does work for controllers that can no longer respond, since driver will attempt to send down a shutdown in this path. Check if the controller is able to receive commands before sending down a shutdown Signed-off-by: Raghava Aditya Renukunta <RaghavaAditya.Renukunta@microsemi.com> Signed-off-by: Martin K.
