From: Roderick Colenbrander <roderick.colenbrander@xxxxxxxx> Hi, The joydev changes introduced by this patch are the result of a discussion on linux-input about handling of features in newer devices, which classic joydev applications may not pick up and confuse. The original motivation was dualshock 3 /4 and thq udraw devices, which expose motion sensors on a subdevice. These got picked up by joydev and confused older applications and users and has been a regression since 4.12. The original patch proposed to filter out motion sensor capability from joydev, but this was 'too wide' of a filter. Ultimately Dmitry suggested for joydev to reject certain devices. This patch introduces an initial blacklist mechanism for joydev. It is used to filter out the motion sensor subdevice on dualshock 3 / 4 and thq udraw. We hope this feature could still make it into 4.14 to minimize impact on our users as this will be a long LTS release.
