From 0ab84cff8befbea342576cd6dc21026d5c9244df Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 18 Jun 2010 01:38:56 -0700 Subject: [PATCH] iwlwifi: read rfkill during resume When resuming from hibernate or suspend, the status of the rfkill switch isn't known since it might have been toggled while the system was asleep. Therefore, we need to read out the status at resume time to make sure the system knows about an up-to-date status.
