From: P Praneesh <quic_ppranees@xxxxxxxxxxx> Currently, PCI read is failing for the registers belonging to SECURITY_CONTROL_WLAN registers. These registers read is required to read the board-id to identify the dual-mac QCN9274 hardware. The failure is because, for these registers (SECURITY_CONTROL_WLAN) offset, ath12k_pci_get_window_start() returns window_start as 0. Due to this PCI read is done without PCI select window and with window_start offset as 0. Hence, fix PCI read and write by doing PCI select window and by using the correct window_start offset - WINDOW_START for SECURITY_CONTROL_WLAN registers.
