I like the idea, minor nit in that we loose the SCSI prefix that tells use which host device printed it. Then again it's a debugging aid, so I don't know that it matters all that much.

Easily solvable with s/""/dev_name(target->scsi_host.shost_gendev)/

Hmm, that may be more ugly than it is worth.
