Linux header arch folder "aarch64" or "arm64"?

So I was trying to compile a wifi driver for a somewhat new usb wifi device and it breaks during compilation because it expects a directory named

/usr/src/<linux-headers>/arch/aarch64

but on NanoPi NEO3 the directory is named (on NanoPI R4S is the same case btw)

/usr/src/<linux-headers>/arch/arm64

In order to make it work, I created a symlink under the "arch" directory called "aarch64" pointing to "arm64" and I was able to compile it. 

Here is what happens when I try to compile it without the symlink:

pablo@callampa:~/repos/github.com/morrownr/rtl8852cu-20240510$ make clean
cd phl ; rm -fr */*/*/*/*.mod.c */*/*/*/*.mod */*/*/*/*.o */*/*/*/.*.cmd */*/*/*/*.ko

My question would be, is it correct? Shouldn't it be named "aarch64" in the first place?
