The -EEXIST errno is reserved by the module loading functionality. When userspace calls [f]init_module(), it expects a -EEXIST to mean that the module is already loaded in the kernel. If module_init() returns it, that is not true anymore. Override the error when returning to userspace: it doesn't make sense to change potentially long error propagation call chains just because it's will end up as the return of module_init().
