patch file to apply

Hi All,

I was trying "devtool modify" on one of my recipes (edk2-firmware.bb/bbappend for aarch64 platform). This recipe (both bb and bbappend) is not including any patches in SRC_URI. Even though its not using any patches, but devtool modify is failed at do_patch. How it can be failed at do_patch, since my recipes was not using any patches. As a hack, we can add do_patch[noexec]= "1" in recipes and bye pass the error. 

steps to replicate 

1. repo init -u ssh://git@git.linaro.org/landing-teams/working/arm/arm-reference-platforms-manifest.git -b master -m corstone700.xml
2. repo sync -j8
3. cd layers/meta-arm
4. git apply edk2-firmware-crostone.diff , I have attached patch file
5. cd -
   export MACHINE=corstone700-fvp
   export DISTRO=poky-tiny
   . ./setup-environment
6. devtool modify edk2-firmware

Error will be looks like below
