2012-05-05charger-manager: Provide cm_notify_event function for in-kernel useChanwoo Choi
By using cm_notify_event function, charger driver can report several charger events (e.g. battery full and external power in/out, etc) to Charger-Manager. Charger-Manager can properly and immediately control chargers by the reported event.

2012-05-05charger-manager: Poll battery health in normal stateChanwoo Choi
Charger-Manager needs to check battery health in normal state as well as suspend-to-RAM state. When the battery is fully charged, Charger-Manager needs to determine when the chargers restart charging. This patch allows Charger-Manager to monitor battery health in normal state and handle operation for chargers after battery is fully charged.

2012-05-05smb347-charger: Convert to regmap APIMika Westerberg
The smb347-charger driver does a lot of read-modify-write to the device registers. Instead of open-coding everything we can take advantage of regmap API which provides nice functions to do this kind of things. In addition there is no need for custom debugfs file for dumping registers as this is already provided by the regmap API.

2012-05-05smb347-charger: Move IRQ enabling to the end of probeMika Westerberg
There is a potential problem if we call smb347_irq_enable() from smb347_irq_init() because smb347_irq_enable() makes the device registers read-only once it returns and smb347_irq_init() expects them to still be read-write. Currently no harm happens because it is the last call we make in smb347_irq_init(). Anyway a better place for enabling IRQs is at the end of probe function and this is also symmetric to call smb347_irq_disable() which is done at the beginning of remove function.

2012-05-04max17042_battery: Fix a couple buffer overflowsDan Carpenter
There are a couple issues here caused by confusion between sizeof() and ARRAY_SIZE(). "table_size" should be the number of elements, but we should allocate it with kcalloc() so that we allocate the correct number of bytes. In max17042_init_model() we don't allocate enough space so we go past the end of the array in max17042_read_model_data() and max17042_model_data_compare(). In max17042_verify_model_lock() we allocate the right amount of space but we call max17042_read_model_data() with the wrong number of elements and also in the for loop we go past the end of the array.

Add error checking on initializing registers and interrupt handler. Initializing registers - lp8727_init_device() : check i2c error during probing the driver. Initializing interrupt handler - lp8727_intr_config() : check an error on creating the irq thread. If an error occurs on probing lp8727 driver, allocated lp8727 driver memory is freed.
