This patch shall be merged through the ARM tree, however, as you see, it
also modifies drivers/net/Kconfig. The easiest for me would be if just I
could get an Acked-by for it. Otherwise, please tell me what you would
prefer - split it into two? Another thing - after a recent cs89x0
discussion, is it a good idea to add another ARM SoC type to the depends
list, or maybe just switch it to "ARM || SUPERH" or something totally
different?
