is the module rename really intentional? If so, it needs to be renamed
to something else as just calling it core may conflict with other
equally badly named modules.

	error: the following would cause module name conflict:
	  GEN     .version
	  drivers/misc/c2port/core.ko
	  drivers/platform/x86/intel/pmc/core.ko
	make[2]: *** [Makefile:1417: modules_check] Error 1
	make[2]: *** Waiting for unfinished jobs....

This builds for me by restoring the previous module names
