No, that isn't possible. Different subsystems manage these different
I issue calls to create /sys entries and I can control the uid and gid of
such inodes. The module options I plan to add will allow setting of the
uid and gid for these inodes.
I issue calls to the v4l core to create character device structures in the
kernel, BUT udevd or devfsd is the entity that creates the /dev entries in
the file system. Therefore I have no way in the driver to control
attributes of such inodes. This is the same point I was making earlier.
It's up to udevd of devfsd to assign those attributes. Out of my hands.
I don't issue any calls in the kernel to create entries under /proc,
however the USB core creates inodes there (under the usbfs mount point
within /proc) for USB devices that exist in the system. So technically
there will be something there that relates to the pvrusb2 device. But I
don't control it, so I can't decide its attributes.
