* Tony Lindgren [off-list ref] [200304 22:55]:

We need to check for errors when calling cpu_pm_enter() and
cpu_cluster_pm_enter(). And we need to bail out on errors as
otherwise we can enter a deeper idle state when not desired.

I'm not aware of the lack of error handling causing issues yet,
but we need this at least for blocking deeper idle states when
a GPIO instance has pending interrupts.

Also, If these changes look OK, it's probably best to apply all
three into some immutable gpio branch against v5.6-rc1 that
I can merge in too if needed.

Regards,

Tony
