Thanks a lot for the explanation(s).

Setting the platform data to NULL should not be necessary. Some
drivers do
this but it's kind of the result of cargo-cult-coding.
+ kfree(time_state);
Btw. I wouldn't call that cargo-cult-coding. It's more defensive
programming as people might not be sure, if there is something around
which still might access the platform data at that point. Ok, there
would be a need for a mutex or similiar if that really could happen, but
I wouldn't call such practices cargo-cult. ;)
