Hi, Yu!

Thank you for the fix, but this wrong check should be just removed, since root case of wrong sysfs file creation was fixed, as Christoph said [1]

Hi, Pavel

Thanks for your response, with the root cause fixed, patch 1 is not
needed anymore. However, the overflow case in patch 2 is still
possible.

Does anyone plan to remove the checking?

Thanks,
Kuai
