+Subject: ASoC: qcom: sc8280xp: Limit speaker digital volumes
+
+From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>
+
+commit 716d4e5373e9d1ae993485ab2e3b893bf7104fb1 upstream.
+
+Limit the speaker digital gains to 0dB so that the users will not damage them.
+Currently there is a limit in UCM, but this does not stop the user form
+changing the digital gains from command line. So limit this in driver
+which makes the speakers more safer without active speaker protection in
+place.
