From e91b1dbdc1f064872a6a2bb2375ae9202dd5e6e0 Mon Sep 17 00:00:00 2001 From: Guo-Fu Tseng Date: Sat, 5 Mar 2016 08:11:56 +0800 Subject: [PATCH] jme: Fix device PM wakeup API usage commit 81422e672f8181d7ad1ee6c60c723aac649f538f upstream. According to Documentation/power/devices.txt The driver should not use device_set_wakeup_enable() which is the policy for user to decide. Using device_init_wakeup() to initialize dev->power.should_wakeup and dev->power.can_wakeup on driver initialization. And use device_may_wakeup() on suspend to decide if WoL function should be enabled on NIC. Reported-by: Diego Viola Signed-off-by: Guo-Fu Tseng Signed-off-by: David S.
