X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b52e8cd3f835869370f8540f1bc804a47a47f02b;p=linux.git KVM: PPC: Book3S HV nestedv2: Fix an error handling path in gs_msg_ops_kvmhv_nestedv2_config_fill_info() The return value of kvmppc_gse_put_buff_info() is not assigned to 'rc' and 'rc' is uninitialized at this point. So the error handling can not work. Assign the expected value to 'rc' to fix the issue.
