Replace direct calls to power supply function attributes with wrappers.
Wrappers provide safe access access in case of unregistering the power
supply (.e.g by removing the driver). Replace:
 - get_property -> power_supply_get_property
 - set_property -> power_supply_set_property
 - property_is_writeable -> power_supply_property_is_writeable

Thanks for looking at patches.

One thing.. Your power_supply_get_property (and friends) check for psy
== NULL. Is it neccessary / good idea? As far as I can tell, it should
not really be NULL...

It is not necessary. I thought it would be a good behavior of such
exported function. You're right that this shouldn't be NULL especially
because previously it was dereferenced.

Other existing power supply exported functions don't check this so maybe
I shouldn't introduce inconsistency.

I'll remove the check and re-spin. I'll found ugly typos in commit
message anyway.

Best regards,
