Subject: wimax: allow user space to send messages once the device is registered
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=de9315fa3a35ebe587cc1a1c88655d095846785e;p=deliverable%2Flinux.git

wimax: allow user space to send messages once the device is registered

It makes sense that the messaging pipe to the device can be used
before the device is fully ready, as long as it is registered with the
stack. Some debugging tools need it.
