This hangs on module load for me. hotkey_inputdev_open() gets
called from input_open_device() with dev->mutex already held, so the
new lock in hotkey_poll_setup() deadlocks:

  INFO: task insmod:28182 is blocked on a mutex likely owned by task insmod:28182.
   hotkey_poll_setup+0x50/0x140 [thinkpad_acpi]
   hotkey_inputdev_open+0x36/0x50 [thinkpad_acpi]
   input_open_device+0x9d/0x130
   kbd_connect+0x8f/0xb0

I guess hotkey_inputdev_close() has the same issue. This was
next-20260929's thinkpad_acpi.c built against 7.1.11.
