If this patch is a Fixes then don't you need the accompanying dts change
as a parallel Fixes too ?
i.e. without the dts update - you won't have the nodes in the dts to
consume => applying this code to the stable kernel absent the dts will
result in no functional change and therefore no bugfix.
I'm not sure if you are asked to put a Fixes here but it seems to be it
should either be dropped or require a parallel Fixes: tag for the dts
and yaml changes.
What is the bug this change fixes in the backport ?
