Krzysztof Kozlowski a2c1d53185 power_supply: ipaq_micro_battery: Check return values in probe 
The return values of create_singlethread_workqueue() and
power_supply_register() calls were not checked and even on error probe()
function returned 0.

1. If allocation of workqueue failed (returning NULL) then further
   accesses could lead to NULL pointer dereference. The
   queue_delayed_work() expects workqueue to be non-NULL.

2. If registration of power supply 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.
