This driver was formerly known as ibm-acpi.
+ Extra functionality will be available if the rfkill (CONFIG_RFKILL)
+ and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
+ Note that if you want ThinkPad-ACPI to be built-in instead of
+ modular, ALSA and rfkill will also have to be built-in.

If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
