+Subject: [PATCH] overlays: Add missing addresses to ads1015/ads1115
+
+The overlays for the ads1015 and ads1115 I2C ADCs omitted the addresses
+in the main device node names. As well as breaking the conventions for
+I2C devices, this prevents the firmware from renaming them when the
+"reg" property is modified, which in turn stops the overlays from being
+instantiated multiple times.
+
