Subject[PATCH AUTOSEL 4.19 014/123] ASoC: sun8i-codec: fix crash on module removal
Date
From: Vasily Khoruzhick <anarsoul@gmail.com>

[ Upstream commit 278df5e5527b633f4882f1680ad58b62a7c07bfe ]

drvdata is actually sun8i_codec, not snd_soc_card, so it crashes
when calling snd_soc_card_get_drvdata().

Drop card and scodec vars anyway since we don't need to
disable/unprepare clocks - it's already done by calling
runtime_suspend()

Drop clk_disable_unprepare() calls for the same reason.

Fixes: 36c684936fae7 ("ASoC: Add sun8i digital audio codec")
