From: Emese Revfy <[email protected]>
This adds the missing __printf attribute which allows compile time
format string checking (and will be used by the coming initify gcc
plugin). Additionally, this fixes the warnings exposed by the attribute.

This modifies code that we get from an external projiect (ACPICA) and
the bugs should be fixed in there in the first place.
Moreover, I'm not sure if adding __printf in acpiosxf.h is a good idea.
Thanks,

Who should get CCed?

Why not? This is going to be needed by the initify plugin to do
correct detection of what's being passed around to functions...

Fortunately, the right people are in the CC list already. :-)

Because it would cause that file to diverge from its upstream
counterpart which would be sort of a problem.

I guess the question is what we will miss if we don't do that
specifically for ACPICA.

Please split above changes into a separate patch.
I'm not sure if the changes can break other compilers.

You can use ACPI_PRINTF_LIKE macro instead.
This can directly go into Linux upstream.
You can prepare a different pull request for ACPICA upstream or
I can help to back port the change.

Hi, Kees and Emese
I just helped to back port the commit here:
https://github.com/acpica/acpica/pull/196/commits/5e64857f
If you can see something wrong in it, please let me know.
Thanks and best regards
