Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
s390/sclp: Fix sclp_init() cleanup on failure
If sclp_init() fails it only partially cleans up: if there are multiple failing calls to sclp_init() sclp_state_change_event will be added several times to sclp_reg_list, which results in the following warning:
------------[ cut here ]------------ list_add double add: new=000003ffe1598c10, prev=000003ffe1598bf0, next=000003ffe1598c10.

Fix this by removing sclp_state_change_event from sclp_reg_list when sclp_init() fails.
