oeqa/kerneldevelopment: Able to apply a single patch to the Linux kernel source
Purpose of kernel development is basically to customize our own recipes kernel by reused existing recipes.   This is an initiative of automating manual kernel development test cases. Applying a single patch to the Linux kernel source is one of the manual test cases of kernel development. Objective of this test is as a developer we can make changes of a file in kernel source and able to apply a single patch to the kernel source.   ref:https://wiki.yoctoproject.org/wiki/Kernel_Development_Test_Cases (From OE-Core rev: 00a5df641b94ef47eec36e742630db7b659102a4) Signed-off-by: Mazliana <mazliana.mohamad@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
