Hi Mauro,

Thanks for working on this.

It seems this is wrong now, as this series doesn't have

https://lore.kernel.org/linux-media/803c39fafdd62efc6f9e4d99a372af2c6955143b.1619621413.git.mchehab+huawei@kernel.org/

I don't fully understand why all the back and forth
happening on this series, but the former Hantro patches
looked good (despite perhaps unclear commit messages).

Any issues just squashing these two commits from "[PATCH v4 00/79] Address some issues with PM runtime at media subsystem":

  media: hantro: use pm_runtime_resume_and_get()
  media: hantro: do a PM resume earlier

?

Thanks,
Ezequiel
