Well from your logs you can see the udev emitted an 'add ' for
wacom_battery, the odd part is that it sends several add for the battery.

It's KERNEL and UDEV, so i think it's OK - no duplicates.

Wacom tablets have a different code from handling the battery, i wrote the
code that'sgeneric for hid devices, and the battery part looks like a lot
when looking to tje wacom one but it doesn't emits 'add ' or 'del '
events...
I'm not kernel dev and after reading docs and digging some code I 'm still
clueless about it...

You might add a few "printk" in hidinput_setup_battery (in kernel
drivers/hid/hid-input.c) to see if everything goes OK.

What's your device?

I have all Apple bluettoth devices (keyboard, mouse, trackpad), this behavior
will happen with any bt device that uses generic HID battery strenth descriptor,
from some docs I read that when registering with udev you must say if the
parent has been registered already, but I can't find the code which describes
that.
There's nothing wrong with my patch regarding the probe for the battery status,
but it clearly doesn't follow some rule to add the power_supply infrastructure,
I wish I could know what is missing...

Best,
