Error! Bad return status for module build on kernel: 5.15.16-200.fc35.aarch64 (aarch64)

Hi!

I'm building the driver following the instructions in the README. This is a NVIDIA Jetson NX board that is running Fedora for ARM.

After executing these commands:

sudo cp /lib/modules/$(uname -r)/build/arch/arm/Makefile /lib/modules/$(uname -r)/build/arch/arm/Makefile.$(date +%Y%m%d%H%M)
sudo sed -i 's/-msoft-float//' /lib/modules/$(uname -r)/build/arch/arm/Makefile
sudo ln -s /lib/modules/$(uname -r)/build/arch/arm /lib/modules/$(uname -r)/build/arch/armv7l

I run the dkms-install.sh and get the following:

[ricky@fedora-jetson-nx Comfast-CF-811AC]$ sudo ./dkms-install.sh

[root@fedora-jetson-nx realtek]# dkms status
rtl8821CU/5.4.1: added

But I still don't see the wifi dongle as an wlan0 interface or anything.

Any hint or pointer please?

Thanks!
