Hmm, the meaning of the code seems to be non obvious. I just looked at sed
replacement and concluded that it's about the file name ending.

Using the full path to the dtb file is not supported by the code anyway, e.g.

   DTB_PATH="${B}/arch/${ARCH}/boot/dts/${DTB}"

would be wrong.

So the correct solution would check both cases

   - full path or only filename and
   - ending is dts or dtb

Correct?
