3.16.47-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: David Carrillo-Cisneros <davi...@google.com>
commit bb8d521f77f3e68a713456b7fb1e99f52ff3342c upstream.
All paths following perf_session__process_event() in __cmd_inject() are
useless if __cmd_inject() is to fail, some depend on a correct
session->evlist.
First commit to add code that depends on session->evlist without checking
error was commmit e558a5bd8b ("perf inject: Work with files"). It has
grown since then.
Change __cmd_inject() to fail immediately after
perf_session__process_event() fails.
