Subject: [PATCH] bsg-lib: introduce a timeout field in struct bsg_job
Git-commit: 31156ec378c2ed10330c8c06bbf36fb7d7a55506
Patch-mainline: v4.17-rc1
References: bsc#1104967,FATE#325924

The zfcp driver wants to know the timeout for a bsg job, so add a field
to struct bsg_job for it in preparation of not exposing the request
to the bsg-lib users.
