Krzysztof Kozlowski	934debf41f	power_supply: twl4030_madc: Check return value of power_supply_register ... commit 68c3ed6fa7 upstream. The return value of power_supply_register() call was not checked and even on error probe() function returned 0. If registering failed then during unbind the driver tried to unregister power supply which was not actually registered. This could lead to memory corruption because power_supply_unregister() unconditionally cleans up given power supply.
