Re: GPU-DRM-TILCDC: Less function calls in tilcdc_convert_slave_node() after error detection

Yes, of course.

Does such an implementation detail correspond to a general software design pattern?

This can occasionally happen.

A special view on software simplicity can also lead to questionable intermediate
function implementation, can't it?

I can agree to this view.

The management of jump labels is just another software development challenge
as usual, isn't it?

How do you think about to clarify the constraints which you imagine a bit more?

I disagree to this conclusion.

Would you like to care a bit more for efficiency and software correctness
around the discussed exception handling?
