Introduce a new helper function, acpi_any_gpe_status_set(), for checking the status bits of all enabled GPEs in one go. It is needed to distinguish spurious SCIs from genuine ones when deciding whether or not to wake up the system from suspend-to-idle. Cc: 5.4+ <stable@vger.kernel.org> # 5.4+ Signed-off-by: Rafael J.
