Subject: [PATCH 5/7] ath10k: remove unnecessary checks
Date: Tue, 15 Oct 2013 21:47:08 +0300 [thread overview]
Message-ID: <20131015184708.14123.49715.stgit@localhost6.localdomain6> (raw)
In-Reply-To: <20131015184548.14123.56949.stgit@localhost6.localdomain6>
From: Michal Kazior <michal.kazior@tieto.com>
mac80211 interface iteration functions that were
used originally iterated over interfaces that
weren't re-added to the driver during recovery.
Since internal vif list is now used it's safe to
remove the safe-guard as internal vif list is
based on add/remove_interface function which
guarantees that vdev is created in FW before it is
iterated over.
