From 84c2c562c101bd84ea0f796b9838296da1bf859e Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Fri, 28 Nov 2008 20:46:22 +0100 Subject: [PATCH] MIPS: RB532: remove useless CF GPIO initialisation As the pata-rb532-cf driver calls gpio_direction_input(), the calls to rb532_gpio_set_func() and rb532_gpio_direction_input() are not needed since the alternate function is automatically being disabled when changing the GPIO pin direction. The later two calls to rb532_gpio_set_{ilevel,istat}() are implicitly being done by the IRQ initialisation of pata-rb532-cf.
