[ Upstream commit da91ece226729c76f60708efc275ebd4716ad089 ]
Like some other Bay and Cherry Trail SoC based devices the Dell Venue
10 Pro 5055 has an embedded-controller which uses ACPI GPIO events to
report events instead of using the standard ACPI EC interface for this.
The EC interrupt is only used to report battery-level changes and
it keeps doing this while the system is suspended, causing the system
to not stay suspended.
Add an ignore-wake quirk for the GPIO pin used by the EC to fix the
spurious wakeups from suspend.
