You should not include my patches in your series. My patch series will
be applied first separately. Just send your own patch with a note that
your patch depends on my patchseries. These guidelines are present are
in Documentation/process/submitting-patches.rst. Make sure to go
through them once.

Also, I will be updating my patchseries with some minor changes, so
this patchset kinda becomes invalid as my patch in here is outdated.
You'll also need to use the updated link when mentioning this
dependency.

Thanks,
