This is a note to let you know that I've just added the patch titled wifi: iwlwifi: mvm: use IWL_FW_CHECK for link ID check to the 6.6-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: wifi-iwlwifi-mvm-use-iwl_fw_check-for-link-id-check.patch and it can be found in the queue-6.6 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 8ea5e824446a131a6be3de38d75e4e9068b1bdb8 Author: Johannes Berg <johannes.berg@xxxxxxxxx> Date: Tue Jun 25 19:51:09 2024 +0300 wifi: iwlwifi: mvm: use IWL_FW_CHECK for link ID check [ Upstream commit 9215152677d4b321801a92b06f6d5248b2b4465f ] The lookup function iwl_mvm_rcu_fw_link_id_to_link_conf() is normally called with input from the firmware, so it should use IWL_FW_CHECK() instead of WARN_ON().
