Subject: [PATCH v2 3/4] PM / s2idle: Rename ->enter_freeze to ->enter_s2idle
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
Rename the ->enter_freeze cpuidle driver callback to ->enter_s2idle
to make it clear that it is used for entering suspend-to-idle and
rename the related functions, variables and so on accordingly.
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
