6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Chenguang Zhao [ Upstream commit e095f249e2209674f6366f6db0383a2b96e19239 ] mtk_handle_irq_rx expects a struct mtk_eth * (matching the request_irq cookie), but mtk_poll_controller incorrectly passed the net_device *. Calling ndo_poll_controller with CONFIG_NET_POLL_CONTROLLER enabled would then crash.
