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)
