+Subject: [PATCH 10/16] driver core: platform: Add support for built-in device
+ properties
+
+Make it possible to pass built-in device properties to platform device
+drivers. This is useful if the system does not have any firmware interface
+like Device Tree or ACPI which provides these.
+
+Properties associated with the platform device will be automatically
+released when the corresponding device is removed.
