2010-12-15workqueue: convert cancel_rearming_delayed_work[queue]() users to ↵Tejun Heo
cancel_delayed_work_sync() cancel_rearming_delayed_work[queue]() has been superceded by cancel_delayed_work_sync() quite some time ago. Convert all the in-kernel users. The conversions are completely equivalent and trivial. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: "David S.

2010-11-18jz4740-battery: Check if platform_data is suppliedLars-Peter Clausen
Currently platform_data is dereferenced without checking whether it is actually set, which can lead to kernel crashes. This patch adds a check which will abort the drivers probe function gracefully if no platform_data is supplied.

2010-11-18isp1704_charger: Detect HUB/Host chargersHeikki Krogerus
To avoid breaking high speed chirp handshaking with CDP chargers, no more then 500mA should be drawn. To make sure of this, utilizing current_max property. After the device has enumerated, it's safe to draw the maximum 1800mA as defined in the Battery Charging Specification. This can be also used with normal USB connection if the controller sends ENUMERATED notification with the milliamps as data. From now on the online property indicates VBUS, present property if there is a charger and current_max the milliamps possible to draw from VBUS.

2010-11-18ds2760_battery: Fix calculation of time_to_empty_nowSven Neumann
A check against division by zero was modified in commit b0525b48. Since this change time_to_empty_now is always reported as zero while the battery is discharging and as a negative value while the battery is charging. This is because current is negative while the battery is discharging. Fix the check introduced by commit b0525b48 so that time_to_empty_now is reported correctly during discharge and as zero while charging.

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.
