From 622d87da7f99b29dde053881bf42c46de7572ce5 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Thu, 27 Dec 2012 10:42:26 +0100 Subject: [PATCH] spi/ath79: remove superfluous chip select code commit f1e8fc9898fd8ca78b7438d3c2e60028d3ae2a34 upstream. 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.
