Hi Greg,
here a new patch for the man page:
o namdev.permissions added
o corrected a few typos
o corrected text for config line format.
owner, group mode are only in namedev.permissions
(don't know what i was dreaming, while i wrote this :))
and a patch for namdev.c comments + debug
o correct 'device device'
o correct permission file to config file
I was looking how to set permissions on the created node.
What is the future of struct device_attr?
Same values are in struct udevice now?
thanks,
Kay
