Summary:                    mdev -s does not populate /dev with devices that
contain a symlink in /sys/class
Description: 
mdev -s does not populate /dev with devices that contain a symlink in
/sys/class: for instance, I have a device /sys/class/graphics/fb0 which is
a symlink to ../../devices/platform/vfb.0/fb0. Because lstat is used in
mdev.c (i.s.o. stat) this device is not taken into account, and a node is
not created in /dev. 

However, changing lstat into stat will cause problems, as there are loops
of symlinks in sysfs. udev itself solves this by only allowing to recurse
2 levels deep in the /sys/class and /sys/block directories. The proposed
patch is in the additional info.
