+Subject: soundwire: qcom: Check device status before reading devid
+
+From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>
+
+commit aa1262ca66957183ea1fb32a067e145b995f3744 upstream.
+
+As per hardware datasheet its recommended that we check the device
+status before reading devid assigned by auto-enumeration.
+
+Without this patch we see SoundWire devices with invalid enumeration
+addresses on the bus.

+Cc: stable@vger.kernel.org
+Fixes: a6e6581942ca ("soundwire: qcom: add auto enumeration support")
