NCR does use pr_debug for the dprintk call, but

It'd be nice to change the last do {} while (0)
to something like:
#define dprintk(flg, fmt, args...) \
do { if (0) pr_debug(fmt, ## args); } while (0)
so the compiler can always verify but not emit any
actual code or format strings.
Also, using macros with ... and __VA_ARGS__ is
a bit more modern.
#define dprintk(flg, fmt, ...) \
do { if (0) pr_debug(fmt, ##__VA_ARGS__); } while (0)
Na, no_printk():
#define dprintk(flg, fmt, ...) no_printk(fmt, ##__VA_ARGS__)
