Hi Frank,

I pulled this and the other two branches you sent yesterday,
the contents all look good. A few minor points:

- The soc@kernel.org and arm@kernel.org addresses both forward
  to soc@lists.linux.dev these days, so just use that one
  directly.

- please split the arch/arm/ code changes from the drivers/*
  branches, since we have separate branches for upstream as well.
  The changes here were fairly small, so I'm not asking you
  to resend them for that here.

- It looks like the automated patchwork bot messages again did
  not work here. The git://git.kernel.org URLs failed to work
  recently and I added a .gitconfig insteadOf rule for it, which
  I think makes the pwbot fail to match the URL and not run
  its maintenance scripts that update patchwork and send the
  email. I've removed the rule again as both now work, but
  you might want to send https:// URLs instead of git://

I will update my script to fix these.
