It depends on the previous patch because PUBKEY_DIR was moved.

1. wireless-regdb does not install custom keys to /etc/wireless-regdb/pubkeys/

2. crypto data would be needlessly embedded into the binaries

3. $(PREFIX)/lib/crda/pukeys/linville.pub.pem would be a waste of space

4. why have all this code supporting embedding of crypto data into binary
   when its no longer needed
