Why does drm-backend fail to start without input devices ?

[Ucan, Emre (ADITG/SW1)]

Hi,

drm_backend_create function fails, if udev_input_init returns  -1. 

udev_input_init returns -1 when no input devices are recognized by udev.

This means, it is not possible to use drm-backend without input devices.

Is there a special reason for this restriction ?

Best regards
