Fixes: 3e4be65eb82c ("Bluetooth: hci_qca: Add poweroff support during hci down for wcn3990") Signed-off-by: Panicker Harish ---- v4: * Used del_timer_sync() instead of mod_timer() to stop the timer and to make sure the handler has finished executing on other CPUs. v3: *Addressed reviewers comments *updated commit message v2: * Addressed the username * The full implementation of IBS is based on timers to that reason we have used timers. v1: initial patch --- drivers/bluetooth/hci_qca.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/bluetooth/hci_qca.c b/drivers/bluetooth/hci_qca.c index dd768a8..9e99311 100644 --- a/drivers/bluetooth/hci_qca.c +++ b/drivers/bluetooth/hci_qca.c @@ -1928,6 +1928,9 @@ static int qca_power_off(struct hci_dev *hdev) hu->hdev->hw_error = NULL; hu->hdev->cmd_timeout = NULL; + del_timer_sync(&qca->wake_retrans_timer); + del_timer_sync(&qca->tx_idle_timer); + /* Stop sending shutdown command if soc crashes. */ if (soc_type != QCA_ROME && qca->memdump_state == QCA_MEMDUMP_IDLE) {
