Subject: linux-next: build warning after merge of the sound-asoc tree

Hi all,

After merging the sound-asoc tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

sound/soc/amd/acp-da7219-max98357a.c: In function 'cz_probe':
sound/soc/amd/acp-da7219-max98357a.c:367:3: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized]
   dev_err(&pdev->dev, "Failed to register regulator: %d\n",
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    ret);
    ~~~~

Introduced by commit

  7b5317aa809f ("ASoC: AMD: Add a fix voltage regulator for DA7219 and ADAU7002")

This is a real bug.
