From 60d418e8540402f4732cce4e8df428e747d79e47 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sun, 20 Apr 2025 09:59:59 +0300 Subject: [PATCH] wifi: iwlwifi: mld: fix BAID validity check Perhaps IWL_FW_CHECK() is a bit misnamed, but it just returns the value of the inner condition. Therefore, the current code skips the actual function when it has the BAID data and makes it crash later when it doesn't. Fix the logic.
