Subject: [PATCH v2] brmcfmac: fix compile when DEBUG is defined

The steps:
1. add "#define DEBUG" in drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c line 61.
2. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=../Out_Linux bcm2835_defconfig
3. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=../Out_Linux/ zImage modules dtbs -j8

Then, it will fail, the compile log described below:

Kernel: arch/arm/boot/zImage is ready
