Possible race condition in `amd_s2idle.py`? -- Crash with `OSError: [Errno 16] Device or resource busy`.

Ahoj,

it seems that there is a race condition with the script amd_s2idle.py.

I did a run of
amd_s2idle-analysis --log /tmp/s2idle.log --duration 2 --wait 2 --count 10 --force (--force is needed because 1. I have an external kernel module (bmi260, for the internal gyroscope of the laptop), 2. the script tells that there are two options in the kernel that could conflict) at some point crashed with

Traceback (most recent call last):
  File "/usr/bin/amd_s2idle-analysis", line 2452, in <module>
    app.test_suspend(duration=duration, wait=wait, count=count)
  File "/usr/bin/amd_s2idle-analysis", line 2286, in test_suspend
    self.execute_suspend()
  File "/usr/bin/amd_s2idle-analysis", line 125, in runner
    ret = func(*args, **kwargs)
          ^^^^^^^^^^^^^^^^^^^^^
  File "/usr/bin/amd_s2idle-analysis", line 2214, in execute_suspend
    with open(p, "w") as w:
OSError: [Errno 16] Device or resource busy

Here is the full terminal output of a run of that script:

And attached the /tmp/s2idle.log.

Note that I manually had to wake up the system, in a first try it did wake up by itself after the 2 seconds, later not.

Regards!
