I am sorry to bring you bad news, but you need to suffer because this is how development goes. If I get presented a generic solution (see Herve's mail) and a specific solution (your driver), for this case I as a maintainer will prefer the generic solution. Generic solutions need more time because there are more things to handle, of course. This is typical for development, I would say, it is not Linux or Free Software specific. I appreciate that you tackled your issue and were open to share it with the community. I see the work being done there. However, there are so many things going on independently that I can't really prevent double development from happening despite it having a high priority for me. As soon as I get aware of people working on similar issues, I connect them. That's what I did here as well. So, if you want upstream supported I2C hot-plugging, you need to wait for Luca's and Herve's work being accepted. Or provide a superior solution. Or, if you want, join the ride. You already have experience in this field (and hardware plus use case), you would be a very welcome contributor, I would say. All the best, Wolfram
