net/wireless: enable wiphy 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 wiphy device to suspend/resume asynchronously. This can take advantage of multicore and improve system suspend/resume speed. Signed-off-by: Zhonghui Fu <zhonghui.fu@linux.intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
