title: Why isn't my Kconfig entry appearing in menuconfig?
body: <p>I have the following entry in drivers/media/video/Kconfig:</p>
  
  <pre><code>config VIDEO_OMAP3
   tristate "OMAP 3 Camera support"
   select VIDEOBUF_GEN
   select VIDEOBUF_DMA_SG
   select OMAP_IOMMU
   depends on VIDEO_V4L2 &amp;&amp; ARCH_OMAP34XX
   ---help---
     Driver for an OMAP 3 camera controller.
  </code></pre>
  
  <p>When I search for VIDEO_OMAP3 in menuconfig I get:</p>
  
  <pre><code>Symbol: VIDEO_OMAP3 [=n]
  Prompt: OMAP 3 Camera support
     Defined at drivers/media/video/Kconfig:836
     Depends on: MEDIA_SUPPORT [=y] &amp;&amp; VIDEO_CAPTURE_DRIVERS [=y] &amp;&amp; VIDEO_V4L2 [=y] &amp;&amp; ARCH_OMAP34XX [=ARCH_OMAP34XX]
     Location:
        -&gt; Device Drivers
           -&gt; Multimedia support (MEDIA_SUPPORT [=y])
              -&gt; Video capture adapters (VIDEO_CAPTURE_DRIVERS [=y])
  </code></pre>
  
  <p>But there is no menuconfig option. I can manually force the object to build by modifying the makefile but I want to ensure that this isn't part of a larger problem.</p>
