spi: spi-gpio.c tests SPI_MASTER_NO_RX bit twice, but not SPI_MASTER_NO_TX
The SPI_MASTER_NO_TX bit (can't do buffer write) wasn't tested. This code was introduced in commit 3c8e1a84 (spi/spi-gpio: add support for controllers without MISO or MOSI pin). This patch fixes a bug in choosing which transfer ops to use. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
