No need to indirect from registered integers to pointers. Just stash the pointers directly in the register struct, and don't even bother registering. This is a small code shrink, speeds register access just a smidgeon, and gets rid of another rude exit() path. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
