you init ret to be default value and then check if ret to be default 
value, it that need?

Suggest not init ret to be -ENOTSUP, so this checking of if (ret == 
-ENOTSUP) is no need.

if (ret) should be enough.

Suggest print error log out of the caller but not in the calling, it 
should be better.
