From 79feedfea7793d91293ab72fac5fc66aae0c6a85 Mon Sep 17 00:00:00 2001 From: Karthikeyan Periyasamy Date: Tue, 28 Sep 2021 12:05:41 +0300 Subject: [PATCH] ath11k: Avoid "No VIF found" warning message Facing below warning prints when we do wifi down in multiple VAPs scenario. warning print: ath11k c000000.wifi: No VIF found for vdev 2 ... ath11k c000000.wifi: No VIF found for vdev 0 In ath11k_mac_get_arvif_by_vdev_id(), we iterate all the radio to get the arvif for the requested vdev_id through ath11k_mac_get_arvif(). ath11k_mac_get_arvif() throws a warning message if the given vdev_id is not found in the given radio. So to avoid the warning message, add the allocated_vdev_map cross check against the given vdev_id before using ath11k_mac_get_arvif() to ensure that vdev_id is allocated in the given radio.
