Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
|diff --git a/drivers/media/usb/uvc/Makefile b/drivers/media/usb/uvc/Makefile
|index c26d12fdb8f4..d86cf22155d1 100644

File to patch:
I moved the title of your question to the body and re-titled your question to something that's shorter. If you feel that this was incorrect, please feel free to change it. In my experience, it's easier to read/understand questions as such.
That is alright. Thanks.
From the output I have the idea that your system has "bigger" problems than not being able to install OpenCV3. Did you install the turtlebot2 packages? That could explain the problem with the realsense camera kernel module.
