From 64bebefcf3195baed3d15dc377e15d1e7121036a Mon Sep 17 00:00:00 2001 From: "Fu, Zhonghui" Date: Thu, 24 Sep 2015 14:06:31 +0800 Subject: HID: enable hid device to suspend/resume asynchronously Now, PM core supports asynchronous suspend/resume mode for devices during system suspend/resume, and the power state transition of one device may be completed in separate kernel thread. PM core ensures all power state transition timing dependency between devices. This patch enables hid devices to suspend/resume asynchronously. This will take advantage of multicore and improve system suspend/resume speed.
