Hmm... please correct me if I misunderstood, but wouldn't that mean that rt2x00 does not have a hardware rfkill line at all, and that instead it has a GPIO pin that is used to communicate the desire to software-rfkill the transmitter... and the driver needs to do everything. If the above is wrong, don't bother with the rest of this email. If the above is correct, you'd not have HARD_BLOCKED at all in rt2x00, just SOFT_BLOCK. Unless you somehow emulated HARD_BLOCKED. Without a real hardware rfkill line, the only way to have HARD_BLOCKED is through software emulation inside the driver, but that is only safe if you are absolutely SURE no firmware or other crap will poke at the hardware behind your back. And if you don't emulate HARD_BLOCKED, you have to handle the input device inside the rt2x00 driver, because the world outside (and that includes the rfkill core and everything else) sure as heck won't know if you SOFT_BLOCKED because of that GPIO pin, or because of something else. -- "One disk to rule them all, One disk to find them.
