Missing put_cpu() in arch/s390/oprofile/hwsampler.c?

[Thomas Meyer]

The function hws_oom_callback() seems to miss a corresponding put_cpu().

Or is this done in another function? I didn't find it.

 Check for get/put_cpu() imbalances

 The simplified semantic patch that makes this report is:

* get_cpu()
... when != put_cpu()
? get_cpu()

Thanks to Julia for the semantic patch to find these kind of errors!
