I'm not saying we should move it to the userspace.
I'm saying this should be "normal" led. drivers/leds/led-huawei-acpi.c, or something. Perhaps this acpi stuff is so similar you don't really need .c code.
And then there should be a "mic muted" trigger. Similar to drivers/leds/trigger/ledtrig-disk.c.
That should give us the flexibility, and should not be really much different from current implementation...
