Subject[PATCH] acpi: Fix format string type mistakes
Message-ID<sP8HL-FW-17@gated-at.bofh.it>
From: Emese Revfy <re.emese@gmail.com>

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,
Rafael

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.
Please clone https://github.com/acpica/acpica, and submit a pull request there to have more ACPICA reviewers.

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

#1545895

From"Moore, Robert" <robert.moore@intel.com>
Date2016-12-21 18:20 +0100
Message-ID<sQSIy-6j6-9@gated-at.bofh.it>
In reply to#1545653
These formatting changes will not compile under:

Gcc 4.4.5
Gcc 5.4.0

The printf formatting stuff is very delicate, as ACPICA has to be compiled under many different compilers.

#1546202

From"Zheng, Lv" <lv.zheng@intel.com>
Date2016-12-22 08:00 +0100
Message-ID<sR5w5-5Rl-9@gated-at.bofh.it>
In reply to#1545895
The original change doesn't handle ACPI_SIZE (which can be UINT64/UINT32 for different architectures) correctly.
I changed it when it is back ported.
This sounds like a different problem.

Thanks and best regards
Lv
