[PATCH 5.17 112/146] perf script: Always allow field data_src for auxtrace

[Greg Kroah-Hartman]

From: Leo Yan <leo.yan@xxxxxxxxxx>

[ Upstream commit c6d8df01064333dcf140eda996abdb60a60e24b3 ]

If use command 'perf script -F,+data_src' to dump memory samples with
Arm SPE trace data, it reports error:

  # perf script -F,+data_src
  Samples for 'dummy:u' event do not have DATA_SRC attribute set. Cannot print 'data_src' field.

This is because the 'dummy:u' event is absent DATA_SRC bit in its sample
type, so if a file contains AUX area tracing data then always allow
field 'data_src' to be selected as an option for perf script.

Fixes: e55ed3423c1bb29f ("perf arm-spe: Synthesize memory event")
