Sadly, this one was my fault - one of my build hacks got in the way :-(

Now, I'm getting this error:
   wl12xx: ERROR could not get firmware ti-connectivity/wl127x-fw-4-sr.bin: -2
But this file is not available at the Linux firmware tree (git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git)

Where can I find it?
