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.
