[PATCH] media: add missing v4l2 dependencies

[PATCH] media: add missing v4l2 dependencies

[Arnd Bergmann]

A few Kconfig warnings showed up recently, pointing to missing
CONFIG_VIDEO_V4L2 dependencies, e.g.:

WARNING: unmet direct dependencies detected for DVB_RTL2832_SDR
  Depends on [n]: MEDIA_SUPPORT [=y] && MEDIA_DIGITAL_TV_SUPPORT [=y] && DVB_CORE [=y] && I2C [=y] && I2C_MUX [=y] && VIDEO_V4L2 [=n] && MEDIA_SDR_SUPPORT [=y] && USB [=y]
  Selected by [y]:
  - DVB_USB_RTL28XXU [=y] && USB [=y] && MEDIA_SUPPORT [=y] && MEDIA_USB_SUPPORT [=y] && I2C [=y] && MEDIA_DIGITAL_TV_SUPPORT [=y] && DVB_USB_V2 [=y] && I2C_MUX [=y] && MEDIA_SUBDRV_AUTOSELECT [=y] && MEDIA_SDR_SUPPORT [=y]

WARNING: unmet direct dependencies detected for MEDIA_TUNER_FC2580
  Depends on [n]: (MEDIA_ANALOG_TV_SUPPORT [=y] || MEDIA_DIGITAL_TV_SUPPORT [=y] || MEDIA_RADIO_SUPPORT [=y] || MEDIA_SDR_SUPPORT [=y]) && MEDIA_SUPPORT [=y] && I2C [=y] && VIDEO_V4L2 [=n]
  Selected by [y]:
  - DVB_USB_AF9035 [=y] && USB [=y] && MEDIA_SUPPORT [=y] && MEDIA_USB_SUPPORT [=y] && I2C [=y] && MEDIA_DIGITAL_TV_SUPPORT [=y] && DVB_USB_V2 [=y] && MEDIA_SUBDRV_AUTOSELECT [=y]

WARNING: unmet direct dependencies detected for VIDEO_OV7670
  Depends on [n]: MEDIA_SUPPORT [=y] && I2C [=y] && VIDEO_V4L2 [=n]
  Selected by [y]:
  - VIDEO_VIA_CAMERA [=y] && MEDIA_SUPPORT [=y] && MEDIA_PLATFORM_SUPPORT [=y] && V4L_PLATFORM_DRIVERS [=y] && FB_VIA [=y]

Some of these apparently stem from a recently added dependency
in the tuner drivers, but I don't know where the VIDEO_VIA_CAMERA
warning got added.

Fixes: 4bdbff4da405 ("media: tuners: Kconfig: add some missing VIDEO_V4L2 dependencies")

I'm not completely convinced the previous patch (4bdbff4da405) was
going in the right direction, it's possible that we should instead
revert that and fix the other problem in a different way.
