The common PM clock management functions may be used for system suspend/resume as well as for runtime PM, so rename them accordingly. Modify kerneldoc comments describing these functions and kernel messages printed by them, so that they refer to power management in general rather that to runtime PM. Signed-off-by: Rafael J.
