Well then nobody can give you a good answer, just guesses based on your
incomplete description of the problem. Showing one or two examples of the
errors would make it possible for people to give good answers.

That seems unlikely. I would guess that the reason is a mismatch between
the driver code you are compiling and the new kernel headers.
