Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
uacce: fix cdev handling in the cleanup path<br />
<br />
When cdev_device_add fails, it internally releases the cdev memory,<br />
and if cdev_device_del is then executed, it will cause a hang error.<br />
To fix it, we check the return value of cdev_device_add() and clear<br />
uacce->cdev to avoid calling cdev_device_del in the uacce_remove.
