From: Arnd Bergmann <arnd@arndb.de>
My previous patch correctly addressed the possible link failure, but as Jani points out, the dependency is now stricter than it needs to be.
Change it again, to allow DRM_FBDEV_EMULATION to be used when DRM_KMS_HELPER and FB are both loadable modules and DRM is linked into the kernel.
As a side-effect, the option is now only visible when at least one DRM driver makes use of DRM_KMS_HELPER. This is better, because the option has no effect otherwise.
