In the Linux kernel, the following vulnerability has been resolved:

fbdev: uvesafb: unregister connector callback on init failure

uvesafb init() registers the v86d connector callback before registering the platform driver. If platform driver register() fails, the function returns the error directly and leaves the connector callback registered.

The later platform-device failure path already unregisters the callback. Add the same cleanup before the final return when platform-driver registration fails.

This issue was identified during our ongoing static-analysis research while reviewing kernel code.
