Hmm...When I can create the device file automatically
then I should also be able to specify the mode. udev
can override this value from kernel if it has another
value from the user. But not having this capability in
the kernel kind of distributes the work (part 1 done
in kernel while part 2 done in user space), which is
not very friendly. Now I will have to distribute a
udev conf file along with my driver.
I can make changes to udev/kernel for this if people
think that this is also desired by others.
