Subject: [PATCH] ASoC: tegra: tegra186_dspk: Fix compile warning with CONFIG_PM=n
Git-commit: b191f01a3756f8d5d0b92bad0a07dac7e373d8be
Patch-mainline: v5.9-rc2
References: jsc#SLE-16518

Fix trivial compile warnings wrt unused functions by adding
__maybe_unused prefix:
  sound/soc/tegra/tegra186_dspk.c:74:12: warning: 'tegra186_dspk_runtime_suspend' defined but not used [-Wunused-function]
  sound/soc/tegra/tegra186_dspk.c:86:12: warning: 'tegra186_dspk_runtime_resume' defined but not used [-Wunused-function]
