From: Vaibhav Hiremath <hvaibhav@xxxxxx>
Fix the build break caused when CONFIG_MEDIA_CONTROLLER
option is disabled and if any sensor driver has to be used
between MC and non MC framework compatible devices.
For example,if tvp514x video decoder driver migrated to
MC framework is being built without CONFIG_MEDIA_CONTROLLER
option enabled, the following error messages will result.
drivers/built-in.o: In function `tvp514x_remove':
drivers/media/video/tvp514x.c:1285: undefined reference to
`media_entity_cleanup'
drivers/built-in.o: In function `tvp514x_probe':
drivers/media/video/tvp514x.c:1237: undefined reference to
`media_entity_init'
The file containing definitions of media_entity_init and
media_entity_cleanup functions will not be built if that
config option is disabled. And this is corrected by
defining two dummy functions.
