Subject: [PATCH] s390: fix invalid return code in sclp_cpi
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9bbc8346fb21fad3f678220b067450e436e45dbf;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] s390: fix invalid return code in sclp_cpi

When the sclp_cpi module is loaded on a system which does not support the
required SCLP call (e.g.  on z/VM), ENOSUPP is returned to user space.  The
correct return value is EOPNOTSUPP.
