From 55285e0fd90b9cf00276f66bb491e28ecdee11d9 Mon Sep 17 00:00:00 2001 From: Lawrence Rust Date: Fri, 8 Apr 2011 09:50:45 -0300 Subject: [PATCH] Fix cx88 remote control input commit 2a164d02dd34c6b49a3f0995900e0f8af102b804 upstream. In the IR interrupt handler of cx88-input.c there's a 32-bit multiply overflow which causes IR pulse durations to be incorrectly calculated. This is a regression caused by commit 2997137be8eba.
