-DDEBUG forces pr_debug to be output and doesn't
allow dynamic_debug for those outputs.

from drivers/i2c/busses/Makefile:

ccflags-$(CONFIG_I2C_DEBUG_BUS) := -DDEBUG

from printk.h:

/* If you are writing a driver, please use dev_dbg instead */
#if defined(DEBUG)
#define pr_debug(fmt, ...) \
	printk(KERN_DEBUG pr_fmt(fmt), ##__VA_ARGS__)
#elif defined(CONFIG_DYNAMIC_DEBUG)
/* dynamic_pr_debug() uses pr_fmt() internally so we don't need it here */
#define pr_debug(fmt, ...) \
	dynamic_pr_debug(fmt, ##__VA_ARGS__)
