[PATCH 1/6] ASoC: tegra: Balance runtime PM count

[Sameer Pujar]

After successful application of volume/mute settings via mixer control
put calls, the control returns without balancing the runtime PM count.
This makes device to be always runtime active. Fix this by allowing
control to reach pm_runtime_put() call.

Fixes: e539891f9687 ("ASoC: tegra: Add Tegra210 based MVC driver")
