In a device driver that I am writing I have something like:
int zr_read (struct virgo_s *board, int reg)
{
return ((int *)board->base)[reg/4];
}
As an unfortunate accident, I was calling this with "board == NULL".
I had expected to see an kernel OOPS. when this happened. None
of this: it simply returned a memory location.
The virgo_s has "base" as its first element.
Anybody know why I didn't see an oops?
