Subject[PATCH v8 12/22] ASoC: tegra: Use device managed resource APIs to get the clock
Date
tegra_asoc_utils uses clk_get() to get the clock and clk_put() to
free them explicitly.

This patch updates it to use device managed resource API
devm_clk_get() so the clock will be automatically released and freed
when the device is unbound and removes tegra_asoc_utils_fini() as
its no longer needed.
