Subject: [PATCH v2] ASoC: rt5682: Fix the vol+ button detection issue
Date: Wed, 25 Aug 2021 12:03:46 +0800	[thread overview]
Message-ID: <20210825040346.28346-1-derek.fang@realtek.com> (raw)

From: Derek Fang <derek.fang@realtek.com>

Fix the wrong button vol+ detection issue with some brand headsets
by fine tuning the threshold of button vol+ and SAR ADC button accuracy.
