Thank you Bruce. After enable kernel-devsrc, the necessary rpm had been
created.
I have one question though, the kernel-devsrc does not seem to include all
the kernel src, that has been fetched and applied patches. Why does it
call kernel-devsrc instead of just kernel-dev? Is there a way to generate
rpm for a complete kernel src with patches applied?
Anyway, I really appreciate you spent your value time to help out.

Unfortunately, kernel-dev rpm does not contains the file in $
{STAGING_KERNEL_BUILDDIR}.

It's a separate recipe. Not part of the bbclass. Build that recipe,
and install the package and you'll get what you want.

There's no bug. kernel-dev doesn't the kernel source by design. Yocto
/ oe has always had its own naming for these packages, and kernel-dev
is the images / artifacts and the directory structure. Now that
kernel-devsrc is available (it wasn't a few years ago), we actually
could remove those directories from kernel.bbclass to clarify things.
