It's not an acceptable approach in kernel development.

A patch like that has zero (actually, negative) value. It simply shouldn't be accepted and regressing to the last "working", most tested version should be the option.

So, all in all, if you are not willing to do your homework well enough, it's better for everybody if you don't bother at all. It wastes both your time and the maintainers' time. Linus' time no less.
