Hi All,

This supersedes

https://lore.kernel.org/linux-pm/3925484.kQq0lBPeGt@rafael.j.wysocki/

the first patch of which proved to be controversial (quite as expected), so it
has been dropped and the patch that was the second one previously is [1/2] now,
and it has not been changed.

Patch [2/2] (previously [3/3]) has been updated to use the full ACQUIRE()/
ACQUIRE_ERR() syntax.

Thanks!
