Subject: i2c-host for v6.18

Hi Wolfram,

here is the pull request for this cycle. I was hoping it would be
more substantial, but I ran into a nasty issue with my gpg setup
that blocked me from pushing to kernel.org for several weeks. The
kernel.org helpdesk helped me sort it out, but unfortunately a
bit too late, so this is all I managed to gather in time.

I am sorry for the disruption. I will set up a backup solution so
that I can avoid this problem in the future.

Thanks and I wish you a great weekend,
Andi
