From 7fd2bf3d325478e6715cce3ede7de641ff596183 Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Thu, 28 Mar 2013 05:07:46 -0700 Subject: [PATCH] Remove GENERIC_GPIO config option GENERIC_GPIO has been made equivalent to GPIOLIB in architecture code and all driver code has been switch to depend on GPIOLIB. It is thus safe to have GENERIC_GPIO removed.
