Subject[PATCH AUTOSEL 5.3 13/89] perf annotate: Return appropriate error code for allocation failures
Date
From: Arnaldo Carvalho de Melo <acme@redhat.com>

[ Upstream commit 16ed3c1e91159e28b02f11f71ff4ce4cbc6f99e4 ]

We should return errno or the annotation extra range understood by
symbol__strerror_disassemble() instead of -1, fix it, returning ENOMEM
instead.
