What about these two much simpler ones that avoid messing with levels
and make your code easier to understand (i.e.: you don't have to figure
out what the level is supposed to mean, the function name will tell):
/* dprintk() for debug messages */
#define dprintk(fmt, args...) do { \
printk(KERN_DEBUG "MYDRV: " fmt , ## args ); } while(0)
/* fundprintk(): as dprintk() but also prints function name */
#define fundprintk(fmt, args...) do { \
printk(KERN_DEBUG "MYDRV: <%s>: " fmt , __FUNCTION__ , ## args ); } while(0);
