A few more minor comments.

Okay, I was not very clear, but in my comment to patch 02/03, I said:
"[...]you could actually remove the Note from the wl1271_acx.h file and
leave it here[...]".  The reasoning to leave it in the C file is that it
is there that you actually set the mac_address to FFFFFFFFFFFF.  So,
remove from the wl1271_acx.h file and put it back on the wl1271_acx.c
file.

No need to have this comment in multiple lines.  You could write just
"Minimal spacing..." and then it will fit nicely in one line ;)

Repeating: No need for the TABs after the #defines.

Alignment.
