CONFIG_MTD_DEBUG vs generic DEBUG support in kernel.h

Hi,
include/linux/mtd/mtd.h contains the following snippet:
#ifdef CONFIG_MTD_DEBUG
#define DEBUG(n, args...) \
do { \
if (n <= CONFIG_MTD_DEBUG_VERBOSE) \
printk(KERN_INFO args); \
} while(0)
which conflicts with the generic debugging support in
include/linux/kernel.h:
#ifdef DEBUG
#define pr_devel(fmt, ...) \
printk(KERN_DEBUG pr_fmt(fmt), ##__VA_ARGS__)
(that is, gcc emits redefinition warnings on modules which
#define DEBUG on their own and also include mtd.h)
Unfortunately, the DEBUG macro is used rather heavily under
drivers/mtd. Should we resolve this somehow or is it better
to just live with it?
