Subject: spi/ath79: remove superfluous chip select code
X-Git-Tag: v3.9-rc1~148^2~21
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f1e8fc9898fd8ca78b7438d3c2e60028d3ae2a34;p=platform%2Fupstream%2Fkernel-adaptation-pc.git

spi/ath79: remove superfluous chip select code

The spi_bitbang driver calls the chipselect function
of the driver from spi_bitbang_setup in order to
deselect the given SPI chip, so we don't have to
initialize the CS line here.
