From 07d35b4270efd08e27cdad9a8d5fa31158cfc4e8 Mon Sep 17 00:00:00 2001 From: Shahar S Matityahu Date: Sun, 10 Feb 2019 10:42:16 +0200 Subject: iwlwifi: use sync nmi in case of init flow failure In case of alive interrupt timeout or any failure in the init flow the driver generates FW nmi. The driver assumes that the nmi will generate SW interrupt. This assumption does not hold and leads to faulty behavior in the recovery flow. Solve this by using sync nmi, this way, even if the driver does not receive SW interrupt, it still starts the recovery flow. Also remove the wait queue from iwl_fwrt_stop_device since the driver is handling the SW interrupt synchronously.
