+Date:		December 2017
+Contact:	Arend van Spriel <aspriel@gmail.com>
+Description:
+		The /sys/devices/.../coredump attribute is only present when the
+		device is bound to a driver, which provides the .coredump()
+		callback. The attribute is write only. Anything written to this
+		file will trigger the .coredump() callback.
+
+		Available when CONFIG_DEV_COREDUMP is enabled.
