No. The idea of depending on a patch that comes later in the series is
because I tried to avoid any regressions in the middle of the series
and also tried to avoid moving code to the "set_infoframes" function
only to remove it later. The "don't write 0 to DIP" patch needs the
set_infoframes function to completely set the state of the control
register, so it basically needed all the previous patches. Any
regression introduced in the middle of the series and then removed
later is an accident.

I could split patches into generational patches, but then we'd have
like 60 patches, most of them one-liners...
