Subject: [PATCH AUTOSEL 6.4 28/54] ASoC: rt5682-sdw: fix for JD event handling in ClockStop Mode0

From: Shuming Fan <shumingf@...ltek.com>

[ Upstream commit 02fb23d72720df2b6be3f29fc5787ca018eb92c3 ]

When the system suspends, peripheral Imp-defined interrupt is disabled.
When system level resume is invoked, the peripheral Imp-defined interrupts
should be enabled to handle JD events.
