Merge tag 'media/v4.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:

  - some build fixes with randconfigs

  - an m88ds3103 fix to prevent an OOPS if the chip doesn't provide the
    right version during probe (with can happen if the hardware hangs)

  - a potential out of array bounds reference in tvp5150

  - some fixes and improvements in the DVB memory mapped API (added for
    kernel 4.16)

* tag 'media/v4.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:
  media: vb2: Makefile: place vb2-trace together with vb2-core
  media: Don't let tvp5150_get_vbi() go out of vbi_ram_default array
  media: dvb: update buffer mmaped flags and frame counter
  media: dvb: add continuity error indicators for memory mapped buffers
  media: dmxdev: Fix the logic that enables DMA mmap support
  media: dmxdev: fix error code for invalid ioctls
  media: m88ds3103: don't call a non-initalized function
  media: au0828: add VIDEO_V4L2 dependency
  media: dvb: fix DVB_MMAP dependency
