Linking issue with THINKPAD_ACPI=y and ALSA subsystem

[Marcel Holtmann]

Hi Henrique,

so I am seeing the current issue when building 2.6.33-rc1 for a X200
machine:

drivers/built-in.o: In function `volume_alsa_notify_change':
thinkpad_acpi.c:(.text+0x16c135): undefined reference to `snd_ctl_notify'
thinkpad_acpi.c:(.text+0x16c14f): undefined reference to `snd_ctl_notify'
drivers/built-in.o: In function `volume_exit':
thinkpad_acpi.c:(.text+0x17000a): undefined reference to `snd_card_free'
drivers/built-in.o: In function `volume_init':

thinkpad_acpi.c:(.init.text+0xa1a3): undefined reference to `snd_ctl_new1'

drivers/built-in.o:(.devinit.data+0xfb8): undefined reference to `snd_ctl_boolean_mono_info'

I do have THINKPAD_ACPI=y in my configuration and CONFIG_SND=m.

Regards

Marcel

That won't work.  Even with the fixes for the Kconfig (either a depends on
SND or a "select SOUND, select SND") you will have to either have both as
modules or both built-in.
