Lenovo removed the extra mixer since the T61 and thereabouts.
Newer Lenovo models only have the mute gate function, and leave
the volume control to the HDA mixer.
Until a way to automatically query the firmware about its audio
control capabilities is discovered (there might not be any), use a

I don't trust the coupled EC writes and SMI calls the current volume
control code does very much, although it is exactly what the IBM DSDTs
seem to do (they never do more than a single step though).
Change the driver to stop issuing SMIs, and just drive the EC directly
to the desired level (DSDTs
Disable volume control by default. It can be enabled at module load
time by a module parameter (volume_control=1).
The audio control mixer that thinkpad-acpi interacts with is fully
functional without any drivers, and operated by hotkeys.
The idea behind the console audio control is that the hum

cause some trouble with the event interface.

We already log the initial state of the hardware rfkill switch (WLSW),
might as well log the state of the softswitches as well.

Before we register the input device, sync the input layer EV_SW state
through a call to input_report_switch(), to avoid issuing a gratuitous
event for the initial state of these switches.
This fixes some annoyances caused by the interaction with rfkill and
EV_SW SW_RFKILL_ALL events.
