From 6eb11a9a311a0f7e5b9b66c18f7498a26c9ec206 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Wed, 6 Oct 2010 11:22:11 +0200 Subject: [PATCH] mac80211: do not requeue scan work when not needed When performing hw scan and not abort it, __ieee80211_scan_completed() is currently called from scan work, so does not need to reschedule work to call drv_hw_scan().
