commit 6371be7aeb986905bb60ec73d002fc02343393b4 upstream.
Commit 3cc2ffe5c16d ("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 24eca2dce0f8 ("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.
