Dear Kukjin,
How would you like to proceed? You did not respond to my email nor to
Bartlomiej's questions.
You questioned the "soc_is_exynos()". I replied but there was no
answer from you. My last reply:

Bartlomiej's justification for it:

... and more.
As for the checking in LSI, I did not receive any answer.
To summarize:
Fixing this with this patch is an optimal way in my humble opinion because:
1. Fixes the problem.
2. Does not introduce regression.
3. Does not remove other features (reverting commits would do).
4. It was tested.
5. We are in late RC and second suspend-to-RAM still does not work.
Reverting commits or developing some kind of new patch (which details
you did not propose) is asking for some other troubles.
Best regards,
Krzysztof
