In case of GPIO -CS lines, the 'ath79_spi_setup_cs' function does the -opposite of that due to the wrong GPIO flags. - -Fix the code to use the correct GPIO flags. - -Reported-by: Ronald Wahl <ronald.wahl@raritan.com> -Signed-off-by: Gabor Juhos <juhosg@openwrt.org> ---- - drivers/spi/spi-ath79.c | 4 ++-- - 1 file changed, 2 insertions(+), 2 deletions(-) - ---- a/drivers/spi/spi-ath79.c -+++ b/drivers/spi/spi-ath79.c -@@ -132,9 +132,9 @@ static int ath79_spi_setup_cs(struct spi - - flags = GPIOF_DIR_OUT; - if (spi->mode & SPI_CS_HIGH) -- flags |= GPIOF_INIT_HIGH; -- else - flags |= GPIOF_INIT_LOW; -+ else -+ flags |= GPIOF_INIT_HIGH; - - status = gpio_request_one(cdata->gpio, flags, - dev_name(&spi->dev)); |
