Subject: [PATCH 0/5] perf: cs-etm: Print auxtrace info even if OpenCSD isn't linked

The auxtrace info header can be useful for debugging, and at the
moment it's possible to record a file without OpenCSD linked but
not view the header even though it should be possible to do.

This patchset tidies up some of the related functions and
improves some of the error messages before making the above
possible in the last commit.

Testing done:

 * Compiled on x86 and Arm both with and without CORESIGHT=1
 * Ran the Coresight tests

Applies to perf/core (0c3852adae8)

James Clark (5):
  perf: cs-etm: Print unknown header version as an error
  perf: cs-etm: Remove unused stub methods
  perf: cs-etm: Tidy up auxtrace info header printing
  perf: cs-etm: Cleanup cs_etm__process_auxtrace_info()
  perf: cs-etm: Print auxtrace info even if OpenCSD isn't linked
