Why !opp_key.freq is okay ? If the user has provided a freq value,
then it must match. Isn't it ?
ok I will fix this in next patch.

We should compare bw too I guess in the same routine.
ok I will add bw similar to level,

Instead dev_pm_opp_find_key_exact() and let the user pass the key

The constructor here must be real, i.e. initialize opp_table here
itself. This is well documented in cleanup.h. Yes there are examples
like this in the OPP core which are required to be fixed too.
ack.
