Subject: ar9170: remove unneeded flush_workqueue()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e351cfbf4e6ccd8bf32555748a49dba5bc93fcb0;p=linux-beck.git

ar9170: remove unneeded flush_workqueue()

cancel_delayed_work_sync() and cancel_work_sync() are already being
used therefore already waiting for all pending work by the driver
to have been completed, no need to flush the mac80211 workqueue.
