That leads to interrupt events erroneously being reported to hiddev for regular control transfers. Prior to 2.6.12 the problem was mitigated by the fact that reporting to hiddev is supressed if the field value has not changed, which is often the case. Said filtering was removed in 2.6.12-rc1 which means any input reports fetched via control transfers result in hiddev interrupt events. This behavior can quickly lead to a feedback loop where a userspace app, in response to interrupt events, issues control transfers which in turn create more interrupt events. This patch prevents input reports that arrive via control transfers from being reported to hiddev as interrupt events.
