   tw9910.c

 - removal of unused cx18 and ivtv alsa mixers

 - the reneseas-ceu driver doesn't depend on soc_camera anymore and
   moved from staging

 - removed the mantis_vp3028 driver, unused since 2009

 - s5p-mfc: add support for version 10 of the MSP

 - added a decoder for imon protocol

 - atomisp: lots of cleanups

 - imx074 and mt9t031: don't depend on soc_camera anymore, being
   promoted from staging

 - added helper functions to better support DVB I2C binding

 - lots of driver improvements and cleanups
