From f5f6b9d9a4959d19fefb4c48ef66de25571f22c3 Mon Sep 17 00:00:00 2001 From: Miri Korenblit Date: Wed, 30 Apr 2025 15:23:17 +0300 Subject: [PATCH] wifi: iwlwifi: mld: don't return an error if the FW is dead If iwl_mld_change_vif_links failed to add the requested link(s) because the FW is dead (error before recovery), there is no point in returning an error value, as the reconfig will re-add the link(s) after the FW is started. Return 0 in that case, and WARN in the others.
