Subject: scsi_transport_fc: Introduce scsi_host_{get,put}()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4cd38e388d547807e89b4bc51a57bdd5fc5ef7df;p=linux-beck.git

scsi_transport_fc: Introduce scsi_host_{get,put}()

Use scsi_host_{get,put}() instead of open-coding these functions.
Compile-tested only.
