I get the following checkpatch warning
CHECK: Macro argument reuse 'reg' - possible side-effects?
#110: FILE: include/linux/soc/brcmstb/brcmstb.h:4:
+#define BRCM_ID(reg) ((u32)reg >> 28 ? (u32)reg >> 16 : (u32)reg >> 8)

Can you fix it and resend. While at that also add commmit log.

Thanks
Kishon
