Subject: spi: spi-davinci: Don't error when SPI_CS_WORD and cs_gpio
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f34ecdbd5661816ce8bbd7511f33181ffa8f4895;p=linux.git

spi: spi-davinci: Don't error when SPI_CS_WORD and cs_gpio

This remove the check and subsequent return of error for the case when
a SPI device requires SPI_CS_WORD and is also configured to use a GPIO
for the CS line.

Commit a134cc414e86 ("spi: always use software fallback for SPI_CS_WORD
when using cs_gio") handles this case now, so this check is no longer
necessary.
