[1] In-tree build (without O=...)

[2] Out-of-tree build and the build directory is right under the source tree
    For example, O=foo

[3] Out-of-tree build and the build directory is not right under the source tree
    For example, O=foo/bar  or O=../foo


__FILE__  points to the source file in relative path for [1] and [2],
and in absolute path for [3].


I guess you are doing [3].  Just try [1] or [2].



FYI, the relative/absolute path is determined by "srctree" of the top Makefile.



ifeq ($(KBUILD_SRC),)
        # building in the source tree
        srctree := .
else
        ifeq ($(KBUILD_SRC)/,$(dir $(CURDIR)))
                # building in a subdirectory of the source tree
                srctree := ..
        else
                srctree := $(KBUILD_SRC)
        endif
endif
