Subject: livepatch: core: Return EOPNOTSUPP instead of ENOSYS
Git-commit: 375bfca3459db1c5596c28c56d2ebac26e51c7b3
Patch-mainline: v5.1-rc1
References: bsc#1071995 fate#323487
As a result of an unsupported operation is better to use EOPNOTSUPP
as error code.
ENOSYS is only used for 'invalid syscall nr' and nothing else.
