Subject[PATCH 3/3] ACPI: EC: Enable noirq stage GPE polling
Date
This patch enables noirq stage GPE polling for the EC driver.

EC is a very special driver, required to work throughout the entire
suspend/resume process. Thus this patch enables IRQ polling for EC during
noirq stages to avoid all kinds of possible issues.

If this commit is bisected to be a regression culprit, please report this
to bugzilla.kernel.org for further investigation.
