[PATCH] prevent udev node creatinon for "class" registration
I've found a /dev/video4linux node and just realized, that libsysfs searches all subdirs for an attribute name. So it found /class/video4linux/video0/dev for the videodev class creation event /class/video4linux and created a node. Just ignore the SUBSYSTEM="class" events now.
