Title
i2c: core: fix NULL-deref on adapter registration failure
Summary
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.
