Well, is it okay to just use the first patch? The fix needs just one bit of data, and I thought that (ab)using the 'priv' pointer would be okay, if a bit hacky. If, over time, the driver needs more private data, it should be clear enought that the existing bit "fiber selected" will also appear in the data structure. Otherwise, the driver would have to allocate a structure with one field, just to remember one bit.
