The mmc_active member of struct mmc_queue_req has a very confusing name: this is certainly not always "active", it is the asynchronous request associated by the mmc_queue_req but it is not guaranteed to be "active" in any sense, such as being running on the host. Simply rename this member to "areq". Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
