[alsa-devel] [PATCH] ASoC: multi-component: TWL4030: Restore registers on removal

[Peter Ujfalusi]

Add back the register restore call, when the codec driver is
removed.
This does not affect normal operation, but it is usefull when
debugging audio through the twl4030 class codecs.

Hello Liam, Mark

I did missed the removal of the register restore from the module
unload path in multi-comp.
This patchs adds it back.
