This > doesn't seem very productive to me. There is at least precedence in the MMC world - have a look at drivers/mmc/host/mmci.c and the struct variant_data... There seem to be a new variant every 6 months or so (I must admit guilt of of making some of them ;-) coming from two different companies. And although it's a primecell (aka amba_bus) device, so the compatibilty string remains the same, the struct amba_id was being extended every time which is pretty much the same thing. Pawel PS. Having said all that I'm hoping the MMCI evolution has finally stopped so no new variants will be needed ;-) -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
