From 0d07025effd3da8b9c74f18448823175f4c63a73 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?David=20H=C3=A4rdeman?= Date: Sat, 30 Oct 2010 22:17:44 +0200 Subject: [PATCH] drivers/media/IR/ir-keytable.c: fix binary search MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The input-large-scancode patches changed the binary search in drivers/media/IR/ir-keytable.c to use unsigned integers, but signed integers are actually necessary for the algorithm to work.
