Something must be missing in the configuration.
With make allyesconfig, you can just compile the file you changed, eg make
drivers/staging/greybus/loopback.o and see if just that file compiles.
Sometimes you can's compile an individual file. In that case, it may be
possible to do make linux/file/path/ (assuming your file is in
linux/file/path/foo.c). The trailing / is essential. make
linux/file/path will do nothing.
