Heh, another duplicated patch:

	https://git.linuxtv.org/mchehab/experimental.git/commit/?h=compile_test&id=687520dc31a88c82c694492423c5d9c503cbdebb

That's why it didn't apply cleanly:

$ patch -p1 -i /tmp/media\:\ platform\:\ fsl-viu\:\ mark\ local\ functions\ \'static\'.patch --merge
patching file drivers/media/platform/fsl-viu.c
Hunk #1 already applied at 238.

Hunk #3 already applied at 262.
Hunk #4 already applied at 806.
Hunk #5 already applied at 817.
Hunk #6 already applied at 1305.

Great minds think alike :-)
