Because the check on the non-existence (encoder == NULL) has already been
done in the implementation of drm_bridge_attach() function, and
drm_bridge_attach() is called earlier. The driver won't get to check point
even if drm_bridge_attach() fails for some reasons, as it will clear the
bridge->encoder to NULL and return a negective error code.

Sorry, my bad.
Therefore, there is no need to check another again. Remove the redundant
codes at the later.

If you end up sending a second version of this patch, please include all
similar patches you have sent at the same time in a patch series,
instead of sending them separately.
I will send a second version to correct spell error and collect and fold them
into a series.
By the way, thanks a lot for you time review my patch and thanks a lot for the
generous.
So happy be reviewed and its my pleasure to have opportunities to talk with
you. Thanks a lot!
