Don't also forget a general 'make' for the whole tree, otherwise undefined symbols that you might have deleted from the module will not show up if you just build one subdirectory.
If resources permit, do a 'make allnoconfig; make', a 'make allmodconfig; make', and a 'make allyesconfig; make' as well. A few randconfig's might not hurt too. This will often shake loose corner configuration cases where either a definition or a use is hiding inside a CONFIG_FOO in the source.
