Re: [Qemu-devel] [RFC PATCH 12/15] input: mouse: add qemu_input_is_absolute()

[John Baboval <baboval@spineless.org>]

Perhaps this should just return the mask instead of a boolean? It would 
be nice at some point to handle a USB HID style device that can send 
both relative and absolute events, for example.

Though perhaps that would be better as future work, since this is a nice 
drop-in replacement for the old call.
