[PATCH] s390: time: make stp_subsys const

From: Ricardo B. Marliere
Date: Sun Feb 04 2024 - 09:25:50 EST


Now that the driver core can properly handle constant struct bus_type,
move the stp_subsys variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
