From 0672120a2ee7c533dfec6db7c3e43450f439e5ff Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Fri, 10 Aug 2012 21:39:38 +0200 Subject: [PATCH] Input: Make sure we follow all EV_KEY events For some EV_KEY types, sending a larger-than-one value causes the input state to oscillate. This patch makes sure this cannot happen, clearing up the autorepeat bypass logic in the process.
