powerpc/perf/hv-24x7: Fail 24x7 initcall if create_events_from_catalog() fails
As Michael pointed out, create_events_from_catalog() fails when we either have: - a kernel bug - some sort of hypervisor misconfiguration - ENOMEM In all the above cases, we can also fail 24x7 initcall. For hypervisor errors, EIO is used so there is something reported in dmesg. Signed-off-by: NLi Zhong <zhong@linux.vnet.ibm.com> Signed-off-by: NMichael Ellerman <mpe@ellerman.id.au>
