Hi,
Changes since v1: ================= 1. Patch 2: fix invalid member used for container_of(). 2. Patch 2: Replace WARN with pr_warn() in __power_supply_register() if parent is missing. Description: ============ This is an idea to fix issue in bq27x00 driver (and probably in others) reported by H. Nikolaus Schaller [0]. The fixes are marked RFC/RFT because: 1. I do not have bq27x00-like device. I confirmed this and tested on modified drivers (max77693, ACPI AC). These drivers are not impacted by the issue but one can easily adjust them to reproduce the problem. 2. The first uevent coming from power_supply_register() is now different because it won't contain device properties. I am not sure how this impacts userspace. Comments are welcomed.
