This is a note to let you know that I've just added the patch titled ath11k: Init hw_params before setting up AHB resources to the 5.19-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: ath11k-init-hw_params-before-setting-up-ahb-resource.patch and it can be found in the queue-5.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 4007e46f54480dab067012ec784dd9afe7572024 Author: Manikanta Pubbisetty <quic_mpubbise@xxxxxxxxxxx> Date: Tue May 17 11:22:41 2022 +0530 ath11k: Init hw_params before setting up AHB resources [ 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.
