Description

In the Linux kernel, the following vulnerability has been resolved: can: hi311x: fix null pointer dereference when resuming from sleep before interface was enabled This issue is similar to the vulnerability in the `mcp251x` driver, which was fixed in commit 03c427147b2d ("can: mcp251x: fix resume from sleep before interface was brought up"). In the `hi311x` driver, when the device resumes from sleep, the driver schedules `priv->restart_work`. However, if the network interface was not previously enabled, the `priv->wq` (workqueue) is not allocated and initialized, leading to a null pointer dereference. To fix this, we move the allocation and initialization of the workqueue from the `hi3110_open` function to the `hi3110_can_probe` function. This ensures that the workqueue is properly initialized before it is used during device resume. And added logic to destroy the workqueue in the error handling paths of `hi3110_can_probe` and in the `hi3110_can_remove` function to prevent resource leaks.
