Hi Philipp,
nice initiative :)

BTW, I could not apply the patch series on linux-next repo.
I applied manually (patch -p1) the #1 patch. The subsequent patches
fail to apply even manually. I'm interested in patch #1 and #4.

Comments below...

For i.MX8, it is necessary sometimes to patch the input jpeg stream,
even for the decoder, due to some limitations in the hardware (example:
only component IDs between 0-3 or 1-4 are supported)

It is useful, I tried it, but it will not work exactly "as is". I'm
sending my initial thoughts as a reply on patch #1
