Comma at end of enum lists

[Jacek Luczak <difrost.kernel@gmail.com>]

Hi All,

I've found that in many enum lists, there's a comma at the end, e.g. 
(arch/x86/kernel/early_printk.c):

enum {
         MAGIC1 = 0xBACCD00A,
         MAGIC2 = 0xCA110000,
         XOPEN = 5,
         XWRITE = 4,
};

Just out of curiosity, is there any particular reason here (no word in 
CodingStyle about that).
