Subject: [PATCH] scsi: sg: Fix type of last blk_trace_setup() argument
Git-commit: 7475c8ae1b7bfc20b0fa586e6fc5155bac5d208b
Patch-mainline: v4.14-rc1
References: bsc#1118139
Avoid that sparse reports the following:
drivers/scsi/sg.c:1114:41: warning: incorrect type in argument 5 (different address spaces)
drivers/scsi/sg.c:1114:41: expected char [noderef] <asn:1>*arg

This patch does not change any functionality.
