Actually, the code is only making sure that PCA963X_MODE2_DMBLNK is on. It is never cleared afterwards. It will be great if you could set that bit on probe and remove those two lines and verify that it works on real hardware. The move of the lock can be a bit expensive. i2c writes can take a while to be performed, this is why only ledout was protected initially.
