[PATCH] perf tools: return errcode in cs_etm__process_auxtrace_info

From: Yue Haibing
Date: Thu Mar 14 2019 - 22:28:40 EST


From: YueHaibing <yuehaibing@xxxxxxxxxx>

'err' is set in err path, but it's not returned to callers.
Also fix a pass zero to PTR_ERR issue.

Fixes: cd8bfd8c973e ("perf tools: Add processing of coresight metadata")
