update-linux-headers: copy standard-headers files one by one
cp_virtio is called for both the asm-s390/ and linux/ directories, so it looks for pci_regs.h and input.h files in asm-s390/ too. This makes little sense. In the next patch we will have the opposite problem; we want to add asm-x86/hyperv.h, and there's also a linux/hyperv.h file with unwanted dependencies on additional Linux uapi headers. We do not want to copy linux/hyperv.h. The solution is to make cp_virtio (now renamed to cp_portable) copy one file only, instead of using the "find" command, and call it multiple times. The new function is really just a reindentation of the old one. Reviewed-by: Michael S.
