From 160bd18e5e545cbb4e5c26f54414485f8ac291ec Mon Sep 17 00:00:00 2001 From: Mikael Pettersson Date: Mon, 1 May 2006 12:16:18 -0700 Subject: [PATCH] [PATCH] x86_64: make PC Speaker driver work The PC Speaker driver's ->probe() routine doesn't even get called in the 64-bit kernels. The reason for that is that the arch code apparently has to explictly add a "pcspkr" platform device in order for the driver core to call the ->probe() routine. arch/i386/kernel/setup.c unconditionally adds a "pcspkr" device, but the x86_64 kernel has no code at all related to the PC Speaker. The patch below copies the relevant code from i386 to x86_64, which makes the PC Speaker work for me on x86_64.
