    Merge tag 'media/v4.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
    
    Pull second batch of media updates from Mauro Carvalho Chehab:
     "This is the second part of the media patches.  It contains the media
      controller next generation patches, with is the result of one year of
      discussions and development.  It also contains patches to enable media
      controller support at the DVB subsystem.
    
      The goal is to improve the media controller to allow proper support
      for other types of Video4Linux devices (radio and TV ones) and to
      extend the media controller functionality to allow it to be used by
      other subsystems like DVB, ALSA and IIO.
    
      In order to use the new functionality, a new ioctl is needed
      (MEDIA_IOC_G_TOPOLOGY).  As we're still discussing how to pack the
      struct fields of this ioctl in order to avoid compat32 issues, I
      decided to add a patch at the end of this series commenting out the
      new ioctl, in order to postpone the addition of the new ioctl to the
      next Kernel version (4.6).
    
      With that, no userspace visible changes should happen at the media
      controller API, as the existing ioctls are untouched.  Yet, it helps
      DVB, ALSA and IIO developers to develop and test the patches adding
      media controller support there, as the core will contain all required
      internal changes to allow adding support for devices that belong to
      those subsystems"
