Subject: [PATCH] ath9k: Fix suspend/resume when no interface is UP
Date: Tue, 28 Jun 2011 18:21:19 +0530 [thread overview]
Message-ID: <1309265479-3206-1-git-send-email-rmanoharan@atheros.com> (raw)
From: Rajkumar Manoharan <rmanohar@qca.qualcomm.com>
When no interface has been brought up, the chip's power
state continued as AWAKE. So during resume, the chip never
been powered up.
