Commit 2f845882ecd2 ("integrity: Add errno field in audit message")
introduced an audit log function that can take an error code. It is
wrapped by integrity_audit_msg() that implicitly sets the error code
argument to zero. The problem is that there are uses of integrity_audit_msg()
such as ima_collect_measurement() that hide the failure cause for
the message.
This series aims to clarify error reasons for failures, and then expose
error codes based on the following criteria:
1. The log depends on a result from earlier callee, and/or
2. The caller function itself returns with that result
ima_release_policy() is the only caller I thought made sense to keep as
is. The message doesn't correlate with a return code, nor does it
depend on a result from an earlier callee in the function.
