[PATCH 1/2] ARM: 9258/1: Fix callchain_trace() return value

[Jinjie Ruan]

perf_callchain_store() return 0 on success, -1 otherwise, fix
callchain_trace() to return correct bool value. So walk_stackframe() can
have a chance to stop walking the stack ahead.

Fixes: 70ccc7c0667b ("ARM: 9258/1: stacktrace: Make stack walk callback consistent with generic code")
