From 38c7c036036c6260606a2a833aaad3794ca22499 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 27 Nov 2009 13:57:15 -0300 Subject: V4L/DVB (13550): v4l: Use the new video_device_node_name function Fix all device drivers to use the new video_device_node_name function. This also strips kernel log messages from the "/dev/" prefix, has the device node location is a userspace policy decision unknown to the kernel.
