From 3e1312f01b508d3f77147bec5286caef074e5d9e Mon Sep 17 00:00:00 2001 From: Aditya Kumar Singh Date: Tue, 8 Apr 2025 11:36:35 +0530 Subject: [PATCH] wifi: ath12k: handle ath12k_core_restart() with hardware grouping Currently, when ath12k_core_restart() is called and the ab->is_reset flag is set, it invokes ieee80211_restart_hw() for all hardware in the same group. However, other hardware might still be in the recovery process, making this call inappropriate with grouping into picture. To address this, add a condition to check if the group is ready. If the group is not ready, do not call ieee80211_restart_hw().
