[ Upstream commit bebcfd2534a63ab7e7325f5337662bc84ca038b6 ]
As part of adding the support of WCN6750 to ath11k, bus_params were moved to hw_params and this regressed the initialization of WCN6750. By the time AHB resources are setup for WCN6750, hw_params will not be initialized and therefore initialization for WCN6750 will fail. This is applicable only for WCN6750, no other device is impacted.
Fix this by moving the initialization of hw_params before setting up AHB resources.
Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00887-QCAMSLSWPLZ-1
