So function of_device_get_match_data() takes as its argument NULL pointer as 'priv' structure is at this stage zeroed, and which cause above kernel crash. priv->dev is filled lines below:Thanks for the report, it was solved in 'net': https://patchwork.kernel.org/project/netdevbpf/patch/20220904215319.13070-1-ansuelsmth@gmail.com/
