Subject: [PATCH] fix I/O memory related compile caused by wrong Kconfig dependencies

From: Hans-Joachim Picht <[email-masked]>
Date: Wed, 21 May 2008 18:05:23 +0200

On s390 linux-next fails with the following build error:

sound/core/memory.c: In function 'copy_to_user_fromio':
sound/core/memory.c:47: error: implicit declaration of function 'memcpy_fromio'
sound/core/memory.c: In function 'copy_from_user_toio':
sound/core/memory.c:82: error: implicit declaration of function 'memcpy_toio'

The problem was introduced with the following commit 
6a5751b42420dce9267d7d915eed8f8673d16fdd ("sound: Convert to menuconfig")
from Takashi's sound-2.6 tree.

Add "depends on HAS_IOMEM" to this menu to make the sound drivers
disappear for s390 which does not have I/O memory.
