Subject: [PATCH 5.10 11/30] ASoC: rt5682: Fix the issue of garbled recording after powerd_dbus_suspend

From: Oder Chiou <oder_chiou@...ltek.com>

[ Upstream commit 6a503e1c455316fd0bfd8188c0a62cce7c5525ca ]

While using the DMIC recording, the garbled data will be captured by the
DMIC. It is caused by the critical power of PLL closed in the jack detect
function.
