From 4ae01c8027ab637d4895b84d91cd7e4c362afdb9 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Mon, 24 Nov 2008 10:29:34 -0800 Subject: [PATCH] remove gpio_expander_omap Now that H3 is converted to use GPIO calls, get rid of the legacy gpio_expander_omap code ... it has no more users. One more needless divergence from mainline gone!
