From 2df910b4c3edcce9a0c12394db6f5f4a6e69c712 Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Sat, 25 Nov 2006 16:35:09 -0200 Subject: [PATCH] ACPI: ibm-acpi: make non-generic bay support optional This patch makes it possible to disable ibm-acpi non-generic bay support, as generic bay support already works well for a number of ThinkPads.
