| Subject: Input: xpad - fix rumble on Xbox One controllers with 2015 firmware |
| |
| [ Upstream commit 540c26087bfbad6ea72758b76b16ae6282a73fea ] |
| |
| Xbox One controllers that shipped with or were upgraded to the 2015 |
| firmware discard the current rumble packets we send. This patch changes |
| the Xbox One rumble packet to a form that both the newer and older |
| firmware will accept. |
| |
| It is based on changes made to support newer Xbox One controllers in |
| the SteamOS brewmaster-4.1 kernel branch. |
