Rpi mailing list owners: Could you please make the list 'unmoderated'? I haven't
subscribe to this list, so I just keep getting the 'Your message to
linux-rpi-kernel awaits moderator approval' for every review comment I post,
which is a spam to me.

Also I won't subscribe to this list unless I work on Rpi. So using moderated
list in LKML is just spamming the reviewers.
