Gentle ping.

Without the patch, the below build failure is produced every time on -next tree:

Building modules, stage 2.
MODPOST 72 modules
ERROR: "of_get_next_parent" [drivers/media/v4l2-core/videodev.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
install kernel and modules


Thanks,
