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
