This ordering can trigger a NULL pointer\ndereference in the serdev controller's receive_buf handler, as it assumes\nserdev->ops is valid when SERPORT_ACTIVE is set.\n\nThis is similar to the issue fixed in commit 5e700b384ec1\n(\"platform/chrome: cros_ec_uart: properly fix race condition\") where\ndevm_serdev_device_open() was called before fully initializing the\ndevice.\n\nFix the race by ensuring client ops are set before enabling the port via\nw1_uart_serdev_open()."
