Hi,
the following patch helps to save 28 kB of RAM if you do not owe a TwinHan DST or clone card. I expected Manu Abraham to write a non destructive interim fix until the new bttv-free bt8xx-backend concept is ready, but instead of this he nacks my docu patch asking me to help testing immature material at the same time.
Reminds me of a situation we already had in the past: 4 unusable kernels, discussions and flame wars. Nearly impossible to discuss, this very strange primadonna. With Gerd Knorr or Peter Hettkamp at his place we all would be a thousand miles farther than we are now. It's just a pity with Manu.
No Signed-off-by as this is partially destructive - I simply do not know better.
