H A Dhid.hdiff d43c17ead879ba7c076dc2f5fd80cd76047c9ff4 Wed Apr 03 09:20:20 CDT 2019 Benjamin Tissoires <benjamin.tissoires@redhat.com> HID: input: make sure the wheel high resolution multiplier is set

Some old mice have a tendency to not accept the high resolution multiplier.
They reply with a -EPIPE which was previously ignored.

Force the call to resolution multiplier to be synchronous and actually
check for the answer. If this fails, consider the mouse like a normal one.
