If you have SCSI enabled and MODULES enabled, this kconfig symbol will be
enabled (=m) automatically.  From drivers/scsi/Kconfig (with # comments):


config SCSI_WAIT_SCAN
	tristate  # No prompt here, this is an invisible symbol.
	default m
	depends on SCSI
	depends on MODULES
# scsi_wait_scan is a loadable module which waits until all the async scans are
# complete.  The idea is to use it in initrd/ initramfs scripts.  You modprobe
# it after all the modprobes of the root SCSI drivers and it will wait until
# they have all finished scanning their buses before allowing the boot to
# proceed.  (This method is not applicable if targets boot independently in
# parallel with the initiator, or with transports with non-deterministic target
# discovery schemes, or if a transport driver does not support scsi_wait_scan.)
#
# This symbol is not exposed as a prompt because little is to be gained by
# disabling it, whereas people who accidentally switch it off may wonder why
# their mkinitrd gets into trouble.
