Subject: [PATCH v2 1/4] PM / s2idle: Rename PM_SUSPEND_FREEZE to PM_SUSPEND_TO_IDLE
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
To make it clear that the symbol in question refers to
suspend-to-idle, rename it from PM_SUSPEND_FREEZE to
PM_SUSPEND_TO_IDLE.
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
