From c24d992ab6b6f067f78585b723fa0c95b3a9c8bf Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Fri, 22 Mar 2013 21:49:06 -0700 Subject: [PATCH] mwifiex: avoid waking up device in awake state We have received interrupt from device means FW is not sleeping. In this case make sure wakeup handler for PCIe is not invoked by setting adapter->pm_wakeup_fw_try to false. Signed-off-by: Avinash Patil Signed-off-by: Bing Zhao Signed-off-by: John W.
