Hi,
This commit:
commit 297d716f6260cc9421d971b124ca196b957ee458

power_supply: Change ownership from driver to core
Change the ownership of power_supply structure from each driver
implementing the class to the power supply core.
has
static void hidinput_cleanup_battery(struct hid_device *dev)
{
- if (!dev->battery.name)
+ if (!dev->battery)
return;
- power_supply_unregister(&dev->battery);
- kfree(dev->battery.name);
- dev->battery.name = NULL;
+ power_supply_unregister(dev->battery);
+ kfree(dev->battery->desc->name);
+ kfree(dev->battery->desc);
+ dev->battery = NULL;
}
Is this OK to access dev->battery after calling power_supply_unregister?
