* Input: synaptics-rmi4 - fix register descriptor subpacket map constructionAndrew Duggan2016-08-22
| | | | | | | | | | | The map_offset variable is specific to the register and needs to be reset in the loop. Otherwise, subsequent register's subpacket maps will have their bits set at the wrong index.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the USB wireless adapter is suspended, the controllers lose their connection. This causes them to start flashing their LED rings and searching for the wireless adapter again, wasting the controller's battery power. Instead, we will tell the controllers to power down when we suspend. This mirrors the behavior of the controllers when connected to the console itself and how the official Xbox One wireless adapter behaves on Windows.
