Subject: spi: nuc900: Set SPI_LSB_FIRST for master->mode_bits if hw->pdata->lsb is true
X-Git-Tag: submit/tizen_common/20140905.094502~694
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2376a9891b6658971bcc5c467acf3772f8a33eda;p=sdk%2Femulator%2Femulator-kernel.git

spi: nuc900: Set SPI_LSB_FIRST for master->mode_bits if hw->pdata->lsb is true

commit f7db1588d6028c97c098bb6445eaabc56a25fed8 upstream.

Otherwise, spi_setup() fails with unsupported mode bits message.
