Subject: [PATCH] scsi: ibmvfc: constify dev_pm_ops structures.
References: bsc#1161951 ltc#183551
Patch-mainline: v4.13-rc1
Git-commit: e4a80c31f2e863295cb2351f23ae486b0513a705
dev_pm_ops are not supposed to change at runtime. All functions
working with dev_pm_ops provided by <linux/device.h> work with const
dev_pm_ops. So mark the non-const structs as const.
