Sorry for not objecting earlier, I confused this with the "msa info req
rejected: 90" error that we see on some 845 devices.
Given that the wlan firmware is signed there's no way for people in the
community to upgrade their firmware, until such version has propagated
through the official channels for the specific device.
As such this patch inhibits the ability of bringing up wifi on devices
such as the Lenovo Yoga C630.
Is there any way we can detect if we're using the "old" firmware?
