s390/ism: add release function for struct device
[ Upstream commit 915e34d5ad35a6a9e56113f852ade4a730fb88f0 ]
According to device_release() in /drivers/base/core.c,
a device without a release function is a broken device
and must be fixed.
The current code directly frees the device after calling device_add()
without waiting for other kernel parts to release their references.
Thus, a reference could still be held to a struct device,
e.g., by sysfs, leading to potential use-after-free
issues if a proper release function is not set.
