Subject: [Update][PATCH] SCSI / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
Subject: SCSI / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM
After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.
Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under
drivers/scsi/ and in include/scsi/scsi_device.h.
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
---
Note: This depends on commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if
PM_SLEEP is selected) which is only in linux-next at the moment (via the
linux-pm tree).
Please let me know if it is OK to take this one into linux-pm.
