There are only 2 uses of the macro.

$ git grep psmouse_printk
drivers/input/mouse/elantech.c:                 psmouse_printk(KERN_DEBUG, psmouse,             \
drivers/input/mouse/elantech.c: psmouse_printk(KERN_DEBUG, psmouse, "PS/2 packet [");
drivers/input/mouse/psmouse.h:#define psmouse_printk(level, psmouse, format, ...)       \
