Yes, you are correct in the fact the naming here is wrong. I used it,
because for legacy reasons, the driver was still called wl1271 at the
time I wrote the patch. Although the driver was named "wl1271" it is
still intended to drive also the wl1273.
Recently, work has been ongoing to change this naming. The wl1271 driver
was renamed to wl12xx to better reflect reality, as you have possibly
noted.
