Comment 9 for bug 580926

I looked into this further, and it seems that the driver is not being built correctly because its build process is not written well for the upstream kernel. This is one of the reasons it exists in the staging drivers tree, where drivers are really just provided on a best effort standpoint. It is possible to build the module separately, and maybe someone has done that (Alex Ainscow?). I have added the firmware to the linux-firmware package so it can be used if you have a working driver.
