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

commit 6371be7aeb986905bb60ec73d002fc02343393b4 upstream.

Commit 3cc2ffe5 ("scsi: sd: Differentiate system and runtime start/stop
management") changed the single bit manage_start_stop flag into 2 boolean
fields of the SCSI device structure. Commit 24eca2dc ("scsi: sd:
Introduce manage_shutdown device flag") introduced the manage_shutdown
boolean field for the same structure. Together, these 2 commits increase
the size of struct scsi_device by 8 bytes by using booleans instead of
defining the manage_xxx fields as single bit flags, similarly to other
flags of this structure.

Avoid this unnecessary structure size increase and be consistent with the
definition of other flags by reverting the definitions of the manage_xxx
fields as single bit flags.

Fixes: 3cc2ffe5 ("scsi: sd: Differentiate system and runtime start/stop management")
Fixes: 24eca2dc ("scsi: sd: Introduce manage_shutdown device flag")
