+Subject: [PATCH] nvmem: qcom-spmi-sdam: register at device init time
+
+There are currently no in-tree users of the Qualcomm SDAM nvmem driver
+and there is generally no point in registering a driver that can be
+built as a module at subsys init time.
+
+Register the driver at the normal device init time instead and let
+driver core sort out the probe order.
