Here is a patch that does that. It also prevents bit 7 (and unused bits)
of configuration register from being reset, as was discussed before:

That second part needs to be backported to the 2.4 driver, and I will do
so.

Additionally, we get rid of a useless label.

The patch is untested (I don't own any supported chip) but quite
straightforward IMHO.
