However, if the network interface was\nnot previously enabled, the `priv->wq` (workqueue) is not allocated and\ninitialized, leading to a null pointer dereference.\n\nTo fix this, we move the allocation and initialization of the workqueue\nfrom the `hi3110_open` function to the `hi3110_can_probe` function.\nThis ensures that the workqueue is properly initialized before it is\nused during device resume. And added logic to destroy the workqueue\nin the error handling paths of `hi3110_can_probe` and in the\n`hi3110_can_remove` function to prevent resource leaks."
