[PATCH 4/4] scsi: Remove CONFIG_SCSI_MULTI_LUN

[Hannes Reinecke <hare@suse.de>]

Obsolete now; either use 'max_lun' if the host supports only a
limited number of LUNs or BLIST_NOLUN if the target has problems
addressing more than one LUN.

-	  Some devices support more than one LUN (Logical Unit Number) in order
-	  to allow access to several media, e.g. CD jukebox, USB card reader,
-	  mobile phone in mass storage mode. This option forces the kernel to
-	  probe for all LUNs by default. This setting can be overriden by
-	  max_luns boot/module parameter. Note that this option does not affect
-	  devices conforming to SCSI-3 or higher as they can explicitely report
-	  their number of LUNs. It is safe to say Y here unless you have one of
-	  those rare devices which reacts in an unexpected way when probed for
-	  multiple LUNs.
