Subject: [PATCH 2/3] spi: spi-davinci: Don't error when SPI_CS_WORD and cs_gpio
Date:   Tue, 18 Sep 2018 12:08:49 -0500
Message-Id: <20180918170850.2749-3-david@lechnology.com>
In-Reply-To: <20180918170850.2749-1-david@lechnology.com>
References: <20180918170850.2749-1-david@lechnology.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
