Mark / Takashi, I may try to split up this series into two or three
smaller patchsets and then the reset/ patch from Philipp Zabel could be
merged by Philipp himself. I primarily want to have the audio resets
fixed and the reset API extended with reset_control_bulk in 5.13 because
this will unblock other patches. Please let me know what you prefer more.
