From 13c24497086418010bf4f76378bcae241d7f59cd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?David=20H=C3=A4rdeman?= Date: Fri, 2 Apr 2010 15:58:30 -0300 Subject: [PATCH] V4L/DVB: Convert drivers/media/dvb/ttpci/budget-ci.c to use ir-core MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Converts drivers/media/dvb/ttpci/budget-ci.c to use ir-core rather than rolling its own keydown timeout handler and reporting keys via drivers/media/IR/ir-functions.c.
