Subject: [PATCH 0/2] ACPI / PM: Dispatch EC GPE early on s2idle resume if LPS0 _DSM is used

Hi All,

The purpose of this series is to address a power button wakeup issue on
some platforms where EC events aren't looked for early enough after
wakeup from suspend-to-idle.

The first patch modifies acpi_ev_detect_gpe() to compute a gpe_event_info
if NULL is passed as its second argument and adds a wrapper around it that
is used in the second patch.

The second patch checks the EC GPE in-line after detecting an SCI wakeup
to avoid missing the wakeup event.

Thanks,
Rafael
