Input: xpad - correctly handle concurrent LED and FF requests

2016-09-15T06:27:46+00:00

[ Upstream commit 7fc595f4c02636eadaeeecfe7bbc45b57c173004 ] Track the status of the irq_out URB to prevent submission iof new requests while current one is active. Failure to do so results in the "URB submitted while active" warning/stack trace. Store pending brightness and FF effect in the driver structure and replace it with the latest requests until the device is ready to process next request. Alternate serving LED vs FF requests to make sure one does not starve another. See [1] for discussion. Inspired by patch of Sarah Bessmer [2].

Input: xpad - fix oops when attaching an unknown Xbox One gamepad

2016-08-10T09:49:26+00:00

commit c7f1429389ec1aa25e042bb13451385fbb596f8c upstream. Xbox One controllers have multiple interfaces which all have the same class, subclass, and protocol. One of the these interfaces has only a single endpoint. When Xpad attempts to bind to this interface, it causes an oops when trying initialize the output URB by trying to access the second endpoint's descriptor. This situation was avoided for known Xbox One devices by checking the XTYPE constant associated with the VID and PID tuple. However, this breaks when new or previously unknown Xbox One controllers are attached to the system. This change addresses the problem by deriving the XTYPE for Xbox One controllers based on the interface protocol before checking the interface number.

remove abs64()

2015-11-09T23:11:24+00:00

Switch everything to the new and more capable implementation of abs(). Mainly to give the new abs() a bit of a workout.
