If there's an error when applying a new state (for example, if a pin is already muxed), old state is not restored. This patch set corrects this behaviour. The first patch is just a small typo fix. The second doesn't introduce any functionnal change, but prepares for the third patch. The third patch undoes what have been done to enable the new state. The last patch re-applies the old state.
