From 8f21b0adfe95907926da1bb0bcd3382b13d0143d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 11 Jan 2013 00:28:01 +0100 Subject: [PATCH] mac80211: call restart complete at wowlan resume time When the driver's resume function can't completely restore the configuration in the device, it returns 1 from the callback which will be treated like a HW restart request, but done directly. In this case, also call the driver's restart_complete() function so it can finish the reconfiguration there.
