From 579e7d60ba0035228aadad69eb2ffeb138c51311 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 11 Dec 2009 11:20:59 -0300 Subject: [PATCH] V4L/DVB (13617): ir: move input_register_device() to happen inside ir_input_register() We'll need to register a sysfs class for the IR devices. As such, the better is to have the input_register_device()/input_unregister_device() inside the ir register/unregister functions. Also, solves a naming problem with V4L ir_input_init() function, that were, in fact, registering a device. While here, do a few cleanups at budget-ci IR logic.
