[PATCH v2 1/3] spi: implemented driver for Cirrus EP93xx SPI controller

[Martin Guy]

and

-         if (espi->tx == 0 && espi->rx == 0)
-                 espi->fifo_level = 0;

since it's always created as 0 and is always reset to 0 by the end of a transfer

and if you like

          /* is transfer finished? */
-         if (espi->tx == t->len && espi->rx == t->len) {
+         if (espi->fifo_level == 0) {

to save a couple of instructions
