| 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
