Could you please integrate this with the framework provided by:

  include/linux/vga_switcheroo.h
  drivers/gpu/vga/vga_switcheroo.c

vga_switcheroo will then automatically expose a sysfs interface.

Find existing vga_switcheroo mux drivers in the tree like this,
they may serve as a template:

  git grep "struct vga_switcheroo_handler" -- :/

Thanks,

Lukas
