[PATCH 2/4] PM: Drop CONFIG_PM_RUNTIME from the driver core

From: Rafael J. Wysocki
Date: Wed Nov 26 2014 - 19:20:37 EST

From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so quite a few
#ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to
depend on CONFIG_PM or even may be dropped entirely in some cases.

Replace CONFIG_PM_RUNTIME with CONFIG_PM in the PM core code.

Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
