[PATCH 6.6 074/269] wifi: iwlwifi: mvm: use IWL_FW_CHECK for link ID check

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johannes Berg <johannes.berg@xxxxxxxxx>

[ 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().
