From 65dd4c1626b396af839881708fdf3bc726a16f73 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 17 Dec 2010 18:37:08 -0800 Subject: [PATCH] omap1: Fix innovator FPGA init for multi-omap No need to call this early from init_irq. Also recent changes initialize GPIO now later, so calling gpio_request from init_irq will make it fail. While at it, also remove the unnecessary EXPORT_SYMBOL.
