Subject: [PATCH] sound/oss/dmasound: fix 'dmasound_setup' defined but not used
Git-commit: 357ad4d898286b94aaae0cb7e3f573459e5b98b9
Patch-mainline: v5.18-rc4
References: git-fixes

We observed: 'dmasound_setup' defined but not used error with
COMPILER=gcc ARCH=m68k DEFCONFIG=allmodconfig build.

Fix it by adding __maybe_unused to dmasound_setup.

Error(s): 
sound/oss/dmasound/dmasound_core.c:1431:12: error: 'dmasound_setup' defined but not used [-Werror=unused-function]
