Technical description
In the Linux kernel, the following vulnerability has been resolved:
i2c: core: fix NULL-deref on adapter registration failure
If adapter registration ever fails the release callback would trigger a
NULL-pointer dereference as the completion struct has not been
initialised.
Note that before the offending commit this would instead have resulted
in a minor memory leak of the adapter name.
