Subject: [PATCH 4/6] iwlwifi: mvm: write queue_sync_state only for sync
Date: Sat,  7 Nov 2020 10:50:09 +0200	[thread overview]
Message-ID: <iwlwifi.20201107104557.51a3148f2c14.I0772171dbaec87433a11513e9586d98b5d920b5f@changeid> (raw)
In-Reply-To: <20201107085011.57943-1-luca@coelho.fi>

From: Avraham Stern <avraham.stern@intel.com>

We use mvm->queue_sync_state to wait for synchronous queue sync
messages, but if an async one happens inbetween we shouldn't
clear mvm->queue_sync_state after sending the async one, that
can run concurrently (at least from the CPU POV) with another
synchronous queue sync.

Signed-off-by: Johannes Berg <johannes.berg@intel.com>
Fixes: 3c514bf831ac ("iwlwifi: mvm: add a loose synchronization of the NSSN across Rx queues")
