The netif_dbg() macro is defined in <linux/netdevice.h>. If the DEBUG macro is defined, it logs a message at 'debug' level, otherwise it does nothing. In net_driver.h we define DEBUG if EFX_ENABLE_DEBUG is defined, but this is too late for those source files that already got a definition of netif_dbg() by including <linux/netdevice.h> Get rid of EFX_ENABLE_DEBUG, and only define and test DEBUG. In mtd.c, we do not use DEBUG as a condition flag but are forced to use the DEBUG macro-function from <linux/mtd/mtd.h>. Undefine DEBUG before including it.
