Subject: [PATCH] ASoC: tegra: tegra210_i2s: Fix compile warning with CONFIG_PM=n
Git-commit: 823279c374669a15a139a29b891dc0d7460262c6

Fix trivial compile warnings wrt unused functions by adding
__maybe_unused prefix:
  sound/soc/tegra/tegra210_i2s.c:167:12: warning: 'tegra210_i2s_runtime_suspend' defined but not used [-Wunused-function]
  sound/soc/tegra/tegra210_i2s.c:179:12: warning: 'tegra210_i2s_runtime_resume' defined but not used [-Wunused-function]
