as we got a bug report about the new Dell laptop with SoundWire audio,
I tried to build a kernel with the downstream SOF patches, then I
noticed that it's not so trivial to get the patches from SOF git tree
that are applicable on top of upstream (either sound or Linus) tree.
Do we have a branch that may contain clean commits on top of the
recent upstream? That is, a branch that is regularly rebased, so that
each commit can be retrieved as a patch. Such a branch will make
upstream submission easier, and it makes easier for distros to take
the downstream patches, too.
