[yocto] How to patch a driver in Linux source tree

[Jeremy Thien]

SRC_URI = "<your kernel git path> file://your-patch-path"

Then place the patch in files subdirectory.

So your tree should look something like:

<your layer>/recipes-kernel/linux/
  linux-raspberrypi_4.4.bbappend
  files/
    <your patch>

Instead of "files", it might be named "linux-raspberrypi".

Hope this helps,
Jeremy
