[PATCH 0/6] hantro: set of small cleanups and fixes

From: Ezequiel Garcia

Hi all,

Here's a few patches with some cleanups and fixes.

The main idea here is to address two issues, and while
at it, clean the driver a bit.

The first issue can be found in Patch 1, when the Request
API is used, the CAPTURE buffer should be returned _before_
the OUTPUT buffer, to avoid waking up userspace prematurely.

I noticed this issue while working on the rkvdec driver,
but this time I've decided to tackle it at the core,
in v4l2_m2m_buf_done_and_job_finish().

The second issue is a simple compliance issue, which is solved
by refactoring the driver, dealing with internal set format
properly.

I suspect it's really late for v5.7, but if we are still
in time, that would be lovely.

Thanks,
Ezequiel
