Subject: [PATCH 09/16] iwlwifi: mvm: Don't sleep in RX path
Date: Tue, 23 Apr 2019 12:10:36 +0300 [thread overview]
Message-ID: <20190423091043.7156-10-luca@coelho.fi> (raw)
In-Reply-To: <20190423091043.7156-1-luca@coelho.fi>
From: Andrei Otcheretianski <andrei.otcheretianski@intel.com>
Don't use cancel_delayed_work_sync() inside the channel switch
notifications as they are handled synchronously as part of the RX path.
Fix that by replacing it with cancel_delayed_work(). This should be safe
as we don't really care whether the work is already started and in such
case we would disconnect anyway.
