## Overview

In the Linux kernel, the following vulnerability has been resolved:

module: fix lost error code from codetag_load_module()

If codetag_load_module() fails, err is not set to reflect the failure
and load_module() returns 0 after the module has been torn down.

Also, if the module is a livepatch, mod->klp_info allocated by
copy_module_elf() leaks on this error path.  Free it via a new
livepatch_cleanup label.

## Affected

- `Linux >= 044d2aee6c575231ed4a24fb3d119bad0937488b < 258310d59a82ea4854bfd9138682bbaac1153b19`
