From 7ea3bbbc8997df1ae7dc4e736d163dabc00f4721 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Tue, 18 Apr 2006 23:18:53 +0100 Subject: [ARM] 3478/1: SharpSL SCOOP: Fix potenial build failure Patch from Richard Purdie Move platform_scoop_config from the SharpSL scoop PCMCIA driver to the SCOOP driver. This avoids build failures when PCMCIA is not built or is modular (scoop.c itself cannot be modular).
