All I can see in the commit log is a vague comment "and fill the proper pdev id in the request message" and nothing else. Please provide a proper explanation for this change and I can then add that to the commit log. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches

Hi Kalle, In patch 701e48a43e15 ("ath11k: add packet log support for QCA6390") , both HTT_PPDU_STATS_CFG_PDEV_ID and pdev_mask were changed, but this pdev_mask calculation is not valid for platforms which has multiple pdevs with 1 rxdma per pdev, as this is writing same value(i.e. 2) for all pdevs. Hence fixed it to consider pdev_idx as well, to make it compatible for both single and multi pd cases.
