SubjectRe: piss poor change in ncr53c8xx/linux-2.1.104
Hi!

> FOR YOUR INFORMATION, THIS DRIVER IS STILL MAINTAINED.

No need to be rude, that person did not have any bad intention. (I was
not that person, FYI).

Ook, what about following patch? (I consider having DELAY() function
when there are generic mdelay() and udelay() functions available bad
thing.)
