My work is currently based on this patch series. Unfortunately with 5.15
I have a bit of trouble picking all the dependencies and run into many
merge conflicts (probably I am missing pieces). I am trying to pick
everything so that I have a good base for my patch. Do you by any chance
have a public git branch with your patch series vdosys1 and all its
dependencies on 5.15? That would make it a lot easier for me to work on
top of it.
Thanks,
Markus
