Should this be cherry-pick of both (they should apply cleanly):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/sound/soc/soc-topology.c?id=e0e7bc2cbee93778c4ad7d9a792d425ffb5af6f7
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/sound/soc/soc-topology.c?id=0298f51652be47b79780833e0b63194e1231fa34
or just the second one adjusted to apply for stable trees?
