i2c: Change prototypes of refcounting functions
Use more standard prototypes for i2c_use_client() and i2c_release_client(). The former now returns a pointer to the client, and the latter no longer returns anything. This matches what all other subsystems do. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: David Brownell <david-b@pacbell.net>
