Subject: [PATCH v5 4/4] ASoC: codecs: wcd9335: drop unused gain hack remnant
Date: Mon, 22 Jan 2024 19:18:19 +0100 [thread overview]
Message-ID: <20240122181819.4038-5-johan+linaro@kernel.org> (raw)
In-Reply-To: <20240122181819.4038-1-johan+linaro@kernel.org>
The vendor driver appears to be modifying the gain settings behind the
back of user space but these hacks never made it upstream except for
some essentially dead code that adds a constant zero to the current gain
setting on DAPM events.
Note that the volume registers still need to be written after enabling
clocks in order for any prior updates to take effect.
