Hi Sandeep,
I was testing this series on my Lenovo Yoga C630, and with this patch
in particular applied, my system will no longer boot. Unfortunately I
don't get any sort of good output at all, I just get hung tasks when
trying to probe things it would seem.
With the other 5 patches in the series applied, the system still boots
and works correctly.

Will check this. Is your controller in host mode or device mode?
Regards
Sandeep
