From: Masami Hiramatsu (Google) <mhiramat@xxxxxxxxxx> commit a457e944df92789ab31aaf35fae9db064e3c51c4 upstream. Fix eprobe syntax test case to check whether the kernel supports the filter on eprobe for filter syntax test command. Without this fix, this test case will fail if the kernel supports eprobe but doesn't support the filter on eprobe.
