[PATCH ath-next 10/17] wifi: ath12k: move MSI config to pci.c

From: Aaradhana Sahu

Date: Thu Oct 08 2026 - 06:31:27 EST


Move the ath12k_wifi7_msi_config array from wifi7/pci.c to pci.c
so it can be shared between QCN9274 and QCN6432 devices. Rename it to
ath12k_msi_config.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.6-01322-QCAHKSWPL_SILICONZ-1
Tested-on: QCN6432 hw1.0 AHB WLAN.WBE.1.6-01322-QCAHKSWPL_SILICONZ-1
