Cool, I have just sent this patch to the stable mailing list, for
inclusion on  v.3.9.y.

More specifically, try the hw/firmware/wl127x-fw-4-sr.bin and the
hw/firmware/wl127x-fw-4-mr.bin (if you're using multirole).  Note that
you need to rename them to wl127x-fw-5-sr.bin and wl127x-fw-5-mr.bin,
respectively.

What we have in the linux-firmware git at the moment are versions
6.3.10.0.133 (singlerole) and 6.5.7.0.42 (multirole).  The new ones in
TI's github repo are 6.3.10.0.136 and 6.5.7.0.46.

If the new firmwares solve your problem, please let me know and I'll
push them to the linux-firmware git repo.

I'd really recommend cherry-picking just what is needed.  It should be
very few patches.  And every time you find a new patch that fixes some
real issue you're seeing, let me know and I'll send to stable.

You're so close to the mainline that it would be silly to use compat
just for a few patches. ;)
