The second return statement can be removed - I suspect some compiler
versions will warn about unreachable code there.

This should be being done by the arch code rather than here, and there's
no code to remove the device on shutdown. This idiom has been used by
some drivers as part of a transition from the old style ASoC stuff where
the I2C device was registered in the CODEC to reduce cross tree issues
but it's best to avoid it for new code.
