Cancel the scheduled scan request only on the vdev that has an active scan running. Currently, ahvif->links_map is used to obtain the links, but this includes links for which no scan is scheduled. In failure cases where the scan fails due to an invalid channel definition, other links which are not yet brought up (vdev not created) may also be accessed, leading to the following trace: Unable to handle kernel paging request at virtual address 0000000000004c8c pc : _raw_spin_lock_bh+0x1c/0x54 lr : ath12k_scan_abort+0x20/0xc8 [ath12k] Call trace: _raw_spin_lock_bh+0x1c/0x54 (P) ath12k_mac_op_cancel_hw_scan+0xac/0xc4 [ath12k] ieee80211_scan_cancel+0xcc/0x12c [mac80211] ieee80211_do_stop+0x6c4/0x7a8 [mac80211] ieee80211_stop+0x60/0xd8 [mac80211] Skip links that are not created or are not the current scan vdev. This ensures only the scan for the matching links is aborted and avoids aborting unrelated links during cancellation, thus aligning with how start/cleanup manage ar->scan.arvif. Also, remove the redundant arvif->is_started check from ath12k_mac_op_cancel_hw_scan() that was introduced in commit 3863f014ad23 ("wifi: ath12k: symmetrize scan vdev creation and deletion during HW scan") to avoid deleting the scan interface if the scan is triggered on the existing AP vdev as this use case is already handled in ath12k_scan_vdev_clean_work().
