From 1a133e0c9dabda23e6693cabfdc1d5106dca5fc2 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Tue, 15 Sep 2009 16:57:24 -0700 Subject: [PATCH] ACPI: make ACPI button funcs no-ops if not built in Yakui pointed out that we don't properly no-op the ACPI button routines if the button driver isn't built in. This will cause problems if ACPI is disabled, so provide stub functions in that case.
