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

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

After merging the sound tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

sound/pci/hda/patch_realtek.c: In function 'alc_fixup_hp_gpio_led':
sound/pci/hda/patch_realtek.c:4134:6: warning: unused variable 'err' [-Wunused-variable]
 4134 |  int err;
      |      ^~~

Introduced by commit

  87dc36482cab ("ALSA: hda/realtek - Add LED class support for micmute LED")

Cheers,
