[PATCH AUTOSEL 5.3 10/89] perf annotate: Fix the signedness of failure returns

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

[ Upstream commit 28f4417c3333940b242af03d90214f713bbef232 ]

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).
