| Hi
| 
| Could someone, please, fix this:
| 
| drivers/media/video/tcm825x.c:
| 
| 853:	if (sensor->platform_data == NULL
| 854:	    && !sensor->platform_data->is_okay())
| 
| I haven't looked through the entire file, so, cannot guarantee, that this 
| is the only place. Maybe, someone could review this file and the whole 
| commit it came in with properly...
| 
| Thanks
| Guennadi
