From 9617040ecab4810363ccab81aac1de3725675c9b Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Fri, 24 Apr 2020 18:48:14 +0300 Subject: iwlwifi: mvm: remove iwlmvm's tfd_q_hang_detect module parameter This should be controlled by the firmware debugging mechanism and not by a module parameter. This has always been true. Remove it and assume it is set.
