I had a look at the patch again. The whole mtd core makes assumptions on parenting, which is totally changed with this patch. There are so many creative ways this can break, I don't believe we are going to continue this route. I propose to revert the patch entirely for now. We need to find another approach, I'm sorry. Alexander, can you please remind me what was your initial problem? I believe you needed to anchor runtime PM on the master device. Can you please elaborate again? Why taking the controller as source (the default, before your change) did not work? Also why was selecting MTD_PARTITIONED_MASTER not an option for you? I'm trying to get to the root of this change again, so we can find a solution fixing "the world" (fast) and in a second time a way to address your problem. Thanks, Miquèl
