Only Nokia was using wl1271 with SPI and since I left Nokia I haven't
had a device with wl1271 connected over SPI, so it has not been tested
at all for a while.
We try to keep SPI working, but we haven't put much effort into it in
the past couple of years. Since we can't test, some people even
proposed removing SPI support altogether, but I preferred not to do it
so that someone (like you!) could try it at some point and report bugs
(as you did!) so we can fix them. ;)
So please, *do* test it and let us know how it goes. If you find any
issues, we'll try to fix them.

That's great to hear! We *do* test the SDIO version of our drivers. ;)
BTW, which kernel version are you using?

This looks reasonable. Do you want to send it in a git patch format so
I can apply? Otherwise I can create the commit myself.
Thanks for your work!
