The framebuffer device driver of kernel supplies sysfs interface to

Currently i know there isn't the generic way for disabling input device
via user interface, so i am looking for the way for disabling
input device on kernel side for above case.

Isn't the expectation here that userspace closes the input device when
it blanks the screen?

Closing the device might be a bit unwieldy, I was thinking more along
the lines of having a way of "accelerating" runtime PM timeout and using
that framework to put the device to sleep.
