Subject: [PATCH 1/5] scsi: BusLogic: Fix missing `pr_cont' use
Update BusLogic driver's messaging system to use `pr_cont' for
continuation lines, bringing messy output:

Also diagnostic output such as with the `BusLogic=TraceConfiguration'
parameter is affected and becomes vertical and therefore hard to read.
This has now been corrected, e.g.:
