From 0beb0a6da8896da14287b1caa77596057690901a Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Tue, 15 Sep 2015 16:26:18 +0300 Subject: spi: au1550: Simplify au1550_spi_setupxfer() SPI core validates both bits_per_word and speed_hz transfer parameters and defaults to spi->bits_per_word and spi->max_speed_hz in case these per transfer parameters are not set. This can simplify a little the au1550_spi_setupxfer() as there is need to check only for valid "struct spi_transfer" pointer.
