SubjectRe: [PATCH v2 19/19] objtool: Detect loading function pointers across noinstr
Just needs a `default:` case.  From personal experience, this warning
helps you track down every switch on an enum when you add a new
enumeration value.

Ignore the dtc-lexer failure, that's a separate known issue.
