   4 Subject: [PATCH] staging: bcm2835-codec: Pass driver context to create
   5  entities
   6
   7 Pass the bcm2835_codec_driver driver context directly into the
   8 bcm2835_codec_create() so that it can be used to store driver global
   9 state. Pass the struct platform_device *pdev by adding it to the driver
  10 global state.
