More of a remark on patch 1 really, note that if you use
POWER_SUPPLY_CHARGE_BEHAVIOUR_TEXT[] here in patch 1, e.g. :

		return sysfs_emit(buf, "%s\n",
				  POWER_SUPPLY_CHARGE_BEHAVIOUR_TEXT[value->intval]);

then you can omit the ps_attr argument in patch 1 already, which in turn
will cause this patch to be simpler / smaller.

Regards,

Hans
