I've read it and I got the impression that a code cleanup is in order
but nevermind, I left it as wrongly indented as it was.

OK, you are right, i am wrong. This functions are back.

I disagree.

I don't have a VLB version to test it on, but by reading the code I
think
that it will work just fine.
Anyway, if I'm wrong I should get a prize for breaking something that

allready broken :-)))) .

Don't worry man, just read the code and you shall find peace of
mind....

It is necessary, unless the purpose of this piece of code is
readability.

If you say that the only way I will get this driver fixed is to keep
it
ugly then I will send you a lame patch that does just that.
