Maybe that other time can use the more typical
pr_<level> mechanisms instead of NS_<LEVEL> too.

As far as I can tell, the only thing that the
NS_<LEVEL> macros do is prefix "error: " and
"warning: " to the output.

"[nandsim] " could be added via pr_fmt and it
could be changed to "nandsim: " for commonality
with the majority of the kernel logging.
