From fdfde0cb79264f88992e72b5a056a3a3284fcaad Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 10 Dec 2021 09:06:11 +0200 Subject: iwlwifi: fix Bz NMI behaviour Contrary to what was stated before, the hardware hasn't changed the bits here yet. In any case, the new CSR is also directly (lower 16 bits) connected to UREG_DOORBELL_TO_ISR6, so if it still changes the changes would be there. Adjust the code and comments accordingly.
