OK, no problem, if that is what is desired for your driver. I just
normally move the author information from the bottom of the file to the
top of the file. As a lot of the linux driver work was (is?) done for
kudos and not for career, I can't just delete author information. That
would not be fair to most of those contributors.
It hasn't been a problem before in all of the other similar commits I've
made, but I can imagine a tool that does a check on the comment block on
the top of a file and complains if it changes, or similar.
Would you prefer something like this instead? It leaves your header
completely untouched, and still gives credit to the original author,
and those lines are also untouched.
I've not re-done build coverage on this yet, but let me know if this is
what you'd prefer.
Thanks,
Paul

Subject: [PATCH] pinctrl: bcm: clean up modular vs. non-modular distinctions
Fixups here tend to be more of a conglomerate of some of the other
repeated/systematic ones we've seen in the earlier pinctrl cleanups.
We remove module.h from code that isn't doing anything modular at
all; if they have __init sections, then replace it with init.h
One driver has a .remove that would be dispatched on module_exit,
and as that code is essentially orphaned, so we remove it. In case
anyone was previously doing the (pointless) unbind to get to that
function, we disable unbind for this one driver as well.
A couple bool drivers (hence non-modular) are converted over to
to builtin_platform_driver().
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We leave the MODULE_AUTHOR and MODULE_LICENSE tag etc. at the bottom
of the file since Broadcom would prefer the comment block at the top
of the file remain unchanged. We just use CPP to take it out of the
picture with an #if 0 / #endif instead.
