[PATCH 1/1] thinkpad-acpi: fix link error to include sound arch

[Hagen Paul Pfeifer]

Thinkpad ACPI depends on sound for resume/suspend/shutdown
events. This fix corrects the Kconfig dependency between
in-kernel build and module build. The preprocessor
directive #ifdef CONFIG_THINKPAD_ACPI_ALSA_SUPPORT
isn't sufficient to handle this build dependency.
