It's not that easy. There are some drivers which are both in-tree and
out-of-tree, for which such a change means adding ifdefs. And there is
i2c-dev.h (the user-space one) which has similar functions, if we
rename only the kernel variants, there will be some confusion. But if
we rename also the user-space variants, then it's up to 2.4 kernel
users to have different names for kernel-space and user-space functions.

All in all I'd say it is not worth the effort. There are many other
tasks where our time will be better used.

Huu, sorry, for some reason I thought that we were still speaking about
i2c-sibyte. Of course I don't have my say about what happens in
drivers/rtc.
