Subject: [PATCH -next] ASoC: sun4i-spdif: drop unnessary snd_soc_unregister_component()

From: Wei Yongjun <weiyongjun1@...wei.com>

It's not necessary to unregister a component registered
with devm_snd_soc_register_component(). Also removed
pointness clk_disable_unprepare() from error path and
snd_soc_unregister_platform() from the remove.

Fixes: f8260afa444b ("ASoC: sunxi: Add support for the SPDIF block")
Signed-off-by: Wei Yongjun <weiyongjun1@...wei.com>
