[PATCH 3/5] PM / Runtime: Correct documented return values for generic PM callbacks

[Geert Uytterhoeven <geert@linux-m68k.org>]

From: Geert Uytterhoeven <geert+renesas@glider.be>

As of commit 05aa55dddb9ee4045c320661068bea78dad6a6e5 ("PM / Runtime:
Lenient generic runtime pm callbacks"), the generic power management
callbacks pm_generic_runtime_suspend() and pm_generic_runtime_resume()
return 0, not -EINVAL, if the device doesn't provide its own callbacks.
