Uwe Kleine-König	37831f8c14	ASoC: tegra: tegra210_ope: Convert to platform remove callback returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

ASoC: tegra: tegra210_ope: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

ASoC: tegra: Add Tegra210 based OPE driver

The Output Processing Engine (OPE) is one of the AHUB client. It has
PEQ (Parametric Equalizer) and MBDRC (Multi Band Dynamic Range Compressor)
sub blocks for data processing. The PEQ block gets samples from the MBDRC
block.

This patch registers OPE driver with ASoC framework. The component driver
exposes DAPM widgets, routes and kcontrols for the device. The DAI driver
exposes OPE interfaces, which can be used to connect different components
in the ASoC layer. Makefile and Kconfig support is added to allow build
the driver.
