Kernel 4.14.x missing module "pas2"

With the current Tumbleweed kernel 4.14.x (i586) I am missing the oss sound driver “pas2.ko”.
Looking at the kernel source, the sources for “pas2” are still there.
The config file for the kernel has no entry for the corresponding “CONFIG_SOUND_PAS”, which is mentioned in the Makefile,
neither as “#CONFIG_SOUND_PAS” nor as “CONFIG_SOUND_PAS=m”, etc…

Is there a reason why this module isn’t built anymore?
