I will address your comment, and send out a new patch. Should I send it out
separately from the series or should I keep it inside?


I would post it separatelly. It doesn't depend on the rest.

OK, I will post it separately. No it does not depend on the rest, but the reset depends on this. So, I am not sure how to enforce that this comes before the rest.


Also, before I send out a new patch, I will need to root cause and resolve
problem found by kernel test robot <fengguang...@intel.com>, and bisected
down to this patch.

Was the report related with this patch?

Yes, they said that the problem was bisected down to this patch. Do you know if there is a way to submit a patch to this test robot?

Thank you,
