From dd2f398ccb73530a99582e972aa57e3ed2fd73c6 Mon Sep 17 00:00:00 2001 From: David Hardeman Date: Sat, 2 Dec 2006 21:16:05 -0200 Subject: [PATCH] V4L/DVB (4875): budget-ci IR: groundwork for following patches This patch lays down some groundwork for later budget-ci patches. The bulk of this consists of moving a few members into a new struct and renaming a few of them. It also allocates extra space for the device name (the "name" field in /proc/bus/input/devices and in the relevant sysfs dir) to avoid truncation and uses snprintf rather than sprintf in case the extra space shouldn't be enough.
