From d8d01a6378db6e3eeb8777a8769c69e455635dc3 Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Sun, 24 Jul 2011 18:33:21 +0100 Subject: [PATCH] x86, olpc: Fix dependency on POWER_SUPPLY As reported by Randy Dunlap, CONFIG_POWER_SUPPLY=m caused a compile error: arch/x86/built-in.o: In function `battery_status_changed': olpc-xo15-sci.c:(.text+0x3acdd): undefined reference to `power_supply_get_by_name' olpc-xo15-sci.c:(.text+0x3ad04): undefined reference to `power_supply_changed' The SCI drivers, as bool, require POWER_SUPPLY to be builtin. Use select to make that a hard requirement and avoid this build failure.
