Merge branch 'topic/kbuild-fixes-for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media build fixes from Mauro Carvalho Chehab:
 "A series of patches that fix compilation on non-x86 archs.

  While most of them are just build fixes, there are some fixes for real
  bugs, as there are a number of drivers using dynamic stack allocation.
  A few of those might be considered a security risk, if the i2c-dev
  module is loaded, as someone could be sending very long I2C data that
  could potentially overflow the Kernel stack.  Ok, as using /dev/i2c-*
  devnodes usually requires root on usual distros, and exploiting it
  would require a DVB board or USB stick, the risk is not high"
