From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
After commit 7a36b901a6eb ("ACPI: OSL: Use a threaded interrupt handler
for SCI") all of the EC code runs in thread context on all systems where
EC events are signaled through a GPE.
It may as well run in thread context on systems using a dedicated IRQ
for EC events signaling, so make it use a threaded handler for that IRQ.
