I think you need to ask the openwrt people which is actual the state of this spi controller driver. In my opinions it has some limitations and why the hell isn't this driver mainline? Maybe there exists already known issues with this driver which are also related to the spi_async receiving buffer issue. I can't help you at this point to fix the spi controller driver. - Alex
