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.
