[PATCH 0/3] ARM: PM: Drop useless checks for PM_SUSPEND_STANDBY

[Geert Uytterhoeven]

	Hi all,

The system suspend implementations for DaVinci, OMAP, and SoCFPGA use
the standard suspend_valid_only_mem() for their
platform_suspend_ops.valid() callbacks.  Hence their
platform_suspend_ops.enter() callbacks will never be called with state
equal to PM_SUSPEND_STANDBY, and checks for this can thus be removed.

Thanks for your comments!

[PATCH 1/3] ARM: davinci: PM: Drop useless check for PM_SUSPEND_STANDBY

[Geert Uytterhoeven]

As DaVinci uses the standard suspend_valid_only_mem() for its
platform_suspend_ops.valid() callback, its platform_suspend_ops.enter()
callback will never be called with state equal to PM_SUSPEND_STANDBY.

Looks good to me. Whats the plan for applying the series. Do you want
the individual machine maintainers to apply their parts. Or some other?

Thanks,

I think the individual machine maintainers is the simplest.

Thanks!

Sounds like you wanted me to pick this up so applying the
omap related patch into omap-for-v4.12/soc.

Thanks,
