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)
