Subject[PATCH V8 1/2] printk: remove tabular output for NULL pointer
Date
Currently pointer() checks for a NULL pointer argument and then if so
attempts to print "(null)" with _some_ standard width. This width cannot
correctly be ascertained here because many of the printk specifiers
print pointers of varying widths.

Remove the attempt to print NULL pointers with a correct width.
