[Hiremath, Vaibhav] Deepthy,

You may want to mention about build failure without MEDIA_CONTROLLER option being enabled, especially if any sensor driver is being used between MC and non-MC framework compatible devices.
For example, OMAP3 and AM3517, where TVP5146 is being used but OMAP3 is based on MC framework and AM3517 is based on simple sub-dev based interface.

[Deepthy Ravi] Ok. I will change description to include that.

Thanks,
Vaibhav
