[PATCH v4 04/15] scsi: fc: provide fc_bsg_to_shost() helper

From: Johannes Thumshirn <hidden>
Date: 2016-11-17 09:33:09
Also in: linux-scsi, lkml
Subsystem: brocade bfa fc scsi driver, emulex/broadcom lpfc fc/fcoe scsi driver, fcoe subsystem (libfc, libfcoe, fcoe), ibm power virtual fc device drivers, linux for powerpc (32-bit and 64-bit), qlogic qla2xxx fc-scsi driver, s390 architecture, s390 zfcp driver, scsi subsystem, the rest · Maintainers: Anil Gurumurthy, Sudarsana Kalluru, Justin Tee, Paul Ely, Hannes Reinecke, Tyrel Datwyler, Madhavan Srinivasan, Nilesh Javali, Heiko Carstens, Vasily Gorbik, Alexander Gordeev, Nihar Panda, "James E.J. Bottomley", "Martin K. Petersen", Linus Torvalds 

Provide fc_bsg_to_shost() helper that will become handy when we're moving from
struct fc_bsg_job to a plain struct bsg_job. Also use this little helper in
the LLDDs.
