Subject: [PATCH 4/4] PM / s2idle: Rename platform operations structure
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
Rename struct platform_freeze_ops to platform_s2idle_ops to make it
clear that the callbacks in it are used during suspend-to-idle
suspend/resume transitions and rename the related functions,
variables and so on accordingly.
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
