+Subject: [PATCH] wifi: ath12k: Fetch regdb.bin file from board-2.bin
+
+Currently, ath12k_core_fetch_regdb() finds regdb.bin file through
+board id's but in board-2.bin file regdb.bin file is present with
+default board id because of which regdb.bin is not fetched.
+
+Add support to fetch regdb.bin file from board-2.bin through
+default board id.
+
+Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
