There's a fix for this but it hasn't been merged yet, will be soon.

Thanks Stephen.

I rolled up a patch to remove that line and put it in my locks-next
branch. It should end up in linux-next soon. I'll plan to send that on
to Linus for v5.16, unless anyone thinks it needs to go in sooner.

Or the number of warnings in a powerpc allyesconfig build got low
enough for me to finally take notice :-)

Maybe switched to a new gcc version?

Yes, that'd be appreciated.

Yeah, it's pretty weird that it never showed up before. I was wondering
for a minute why I was CC'ed on a sound merge issue :-)

Do you want me to send a patch or just commit something to suppress
this?

Yes, or simply zero-ing the variable in onyx_read_register().  The
current code ignores the read error and it's been OK over a decade :)

linux-next: build warning after merge of Linus' tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 657 bytes --]

Hi all,

After merging the origin tree, today's linux-next build (powerpc
allyesconfig) produced this warning:

sound/aoa/codecs/onyx.c: In function 'onyx_snd_single_bit_get':
sound/aoa/codecs/onyx.c:377:37: warning: 'c' may be used uninitialized in this function [-Wmaybe-uninitialized]
  ucontrol->value.integer.value[0] = !!(c & mask) ^ polarity;
                                     ^~~~~~~~~~~~

Introduced by commit

  f3d9478b2ce4 ("[ALSA] snd-aoa: add snd-aoa")

This warning has been around for a long time.  It could possibly be
suppressed by checking for errors returned by onyx_read_register().
