spi: omap-uwire: Remove needless bits_per_word and speed_hz tests
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 allows to remove two needless tests from uwire_txrx() and uwire_setup_transfer(). Signed-off-by: Jarkko Nikula <jarkko.nikula@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
