Subject: [PATCH] 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

This has nothing to do with Raspberry Pi, so the title should be:
