[ Upstream commit 4ecf56f4b66011b583644bf9a62188d05dfcd78c ] The MSE102x doesn't provide any interrupt register, so the only way to handle the level interrupt is to fetch the whole packet from the MSE102x internal buffer via SPI. So in cases the interrupt handler fails to do this, it should return IRQ_NONE. This allows the core to disable the interrupt in case the issue persists and prevent an interrupt storm.
