From 3005c63a3673eaf3202b2e0c951e5092539bf758 Mon Sep 17 00:00:00 2001 From: Pradeep Kumar Chitrapu Date: Wed, 12 Jun 2024 15:53:36 -0700 Subject: [PATCH] wifi: ath12k: fix legacy peer association due to missing HT or 6 GHz capabilities Currently SMPS configuration failed when the Information Elements (IEs) did not contain HT or 6 GHz capabilities. This caused legacy peer association to fail as legacy peers do not have HT or 6 GHz capabilities. Fix this by not returning an error when SMPS configuration fails due to the absence of HT or 6 GHz capabilities.
