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
