if that's all functionally correct, then this is a nice cleanup. Though
from the above changelog its hard to tell because it merily tells WHAT the
patch does, but not WHY. The WHY is the important information for a
reviewer who is not familiar with the particular piece of code/hardware.

Can you please amend the changelog with proper explanations why a
particular piece of code is not needed or has to be changed to something
else?

Thanks,
