From: Jérôme Pouiller <jerome.pouil...@silabs.com> When a station is removed, the driver check that all the Tx frames were correctly sent. However, the station can be removed before all the Tx frames were acknowledged and a false positive warning can be emitted.
The previous commit has added a trace when driver received an acknowledge for a non-existent station. It appear that these events are perfectly correlated and there is no leak. Now, the subject is perfectly understood. Remove the warning. Just keep a debug trace in case we have any doubt in the future. In the past, the subject has already been discussed here: https://lore.kernel.org/driverdev-devel/6287924.ghGFUMk3OD@pc-42/ Fixes: 4bbc6a3e7ad0 ("staging: wfx: make warning about pending frame less scary") Signed-off-by: Jérôme Pouiller <jerome.pouil...@silabs.com> --- drivers/staging/wfx/sta.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/staging/wfx/sta.c b/drivers/staging/wfx/sta.c index f448957c1a92..6015cd2c4d8a 100644 --- a/drivers/staging/wfx/sta.c +++ b/drivers/staging/wfx/sta.c @@ -441,8 +441,10 @@ int wfx_sta_remove(struct ieee80211_hw *hw, struct ieee80211_vif *vif, for (i = 0; i < ARRAY_SIZE(sta_priv->buffered); i++) if (sta_priv->buffered[i]) - dev_warn(wvif->wdev->dev, "release station while %d pending frame on queue %d", - sta_priv->buffered[i], i); + // Not an error if paired with trace in + // wfx_tx_update_sta() + dev_dbg(wvif->wdev->dev, "release station while %d pending frame on queue %d", + sta_priv->buffered[i], i); // See note in wfx_sta_add() if (!sta_priv->link_id) return 0; -- 2.26.2 _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
