Look at the code and stop the hand-waving generalities.

The other motto of the kernel is do it once right. If this code is not
there every thing that just wants to turn on a LED for a half second needs
to do their own timer. I have a couple drivers where I use some LED's on the
GPIO pins and I don't want to do a timer in each one of them.
