So, the following is an update containing a patch ([1/5]) that fixes the "creation of sysfs files after the device have been registered" problem. Hopefully. :-) Patches [2-3/5] are the previous [1-2/4] and they are almost identical as before, so I added the ACKs you gave for them. Patch [4/5] is the sysfs one with the internal function placed in the internal header. Patch [5/5] is a rework of the one exposing the lists of power resources as directories containing symbolic links. Please let me know if you are fine with this.
