Subject: [PATCH] ath11k: Init hw_params before setting up AHB resources
Date: Tue, 17 May 2022 11:22:41 +0530	[thread overview]
Message-ID: <20220517055241.15885-1-quic_mpubbise@quicinc.com> (raw)

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

Fixes: 00402f49d26f ("ath11k: Add support for WCN6750 device")
