From cf912ca1a3c3d2e6fcacb6568e66f72cca05277d Mon Sep 17 00:00:00 2001 From: Dmitry Antipov Date: Tue, 3 Oct 2023 12:20:46 +0300 Subject: [PATCH] wifi: iwlwifi: drop NULL pointer check in iwl_mvm_tzone_set_trip_temp() Since 'tz_device' is an in-place member of 'struct iwl_mvm', it can't be NULL and so relevant check may be dropped. Compile tested only. Found by Linux Verification Center (linuxtesting.org) with SVACE.
