+Subject: [PATCH] staging: bcm2835-codec: Pass driver context to create
+ entities
+
+Pass the bcm2835_codec_driver driver context directly into the
+bcm2835_codec_create() so that it can be used to store driver global
+state. Pass the struct platform_device *pdev by adding it to the driver
+global state.
