Subject: [PATCH 20/24] perf annotate: Fix the signedness of failure returns
Date:   Tue,  1 Oct 2019 08:12:12 -0300

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Callers of symbol__annotate() expect a errno value or some other
extended error value range in symbol__strerror_disassemble() to
convert to a proper error string, fix it when propagating a failure to
find the arch specific annotation routines via arch__find(arch_name).
