From 6b8cc3306e78490bda26815b04c786d8e1fc1489 Mon Sep 17 00:00:00 2001 From: Josef Ahmad Date: Tue, 9 Apr 2013 18:25:34 +0100 Subject: [PATCH] spi-gpio: init CS before spi_bitbang_setup() spi_bitbang_setup() deasserts the chip select line to initialise the device. The chip select GPIO line is obtained from spi_gpio->cs_gpios[] private data. Currently, devices that are not registered under devicetree environment will call into spi_bitbang_setup() with stale cs_gpios[]. This patch ensures spi_gpio->cs_gpios[] is always initialised prior to calling spi_bitbang_setup().
