updated fix below - another randconfig also pointed it out that there's
an I2C dependency. (I cannot possibly do a full analysis of the
dependencies of this code so i keep fixing up dependencies as they
occur.)

Subject: media/video/sound build fix, TEA5761/TEA5767
From: Ingo Molnar <mingo@elte.hu>

x86.git randconfig testing found the following build error:

drivers/built-in.o: In function `v4l2_i2c_drv_attach_legacy':
tuner-core.c:(.text+0x1a829d): undefined reference to `v4l2_i2c_attach'
drivers/built-in.o: In function `tuner_command':
tuner-core.c:(.text+0x1a971c): undefined reference to `v4l_printk_ioctl'

the reason is that the TEA5761/TEA5767 tuner code is dependent on
(legacy?) V4L infrastructure like v4l2_i2c_attach, by virtue of
drivers/media/video/tuner-core.c including media/v4l2-i2c-drv-legacy.h
and ./sound/i2c/other/Makefile doing:

snd-tea575x-tuner-objs := tea575x-tuner.o

for now i solved this via adding a VIDEO_V4L2_COMMON dependency
to MEDIA_TUNER - but i suspect there might be a better fix as well.
