  GCC 13.2.0 compiler issued the following warning:

Fixing the format specifier in call to ksft_print_msg() according to the
compiler suggestion silences the warning.

If this is the issue then...

...why are we not using an unsigned format specifier here?  I am very
suprised this doesn't continue to warn.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

I double-checked and there is no warning, but I will fix it as you
suggested.

I am just looking at the `git log --oneline tools/testing/selftests/alsa`
and I can't seem to get inspiration.

I guess I can keep the Acked-by tags. Will the patchwork find the tag in
the v1 patch set?

Sorry for the lag in [PATCH v1 4/4]. I thought I pressed submit, but I
obviously did not.

Thanks,
Mirsad

No, you need to include it.

Great. Sent v2 for review.

I heard that there is a rule "one version per day or when confirmed"?

Nevertheless, these are minor fixes in the error reporting logic (though
no change is small enough to bee taken lightly), so I am sending now
because I don't know about the load tomorrow.

Please find v2 of the patch set on the LKML.

Kept two ACKs (code unchnaged), two left to review.

Thanks,
Mirsad

Thx.

Fixed in v2.

Thanks,
