John, Your commit 78865eacb4aa ("MIPS: ralink: add illegal access driver") landed in today's linux-next (ie, next-20141027). That commit dates back to May 16, 2013! It adds a driver that is built if CONFIG_RALINK_ILL_ACC is set. But there's no Kconfig symbol RALINK_ILL_ACC. I assume that patch that adds this symbol is queued somewhere. Is that correct? Paul Bolle
