From dd21dfc645d5dce0657af78761b3fa11a3a95398 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 20 Jan 2016 10:39:23 +0100 Subject: rfkill: disentangle polling pause and suspend When suspended while polling is paused, polling will erroneously resume at resume time. Fix this by tracking pause and suspend in separate state variable and adding the necessary checks. Clarify the documentation on this as well.
