Comment:
It would error out when building with dkms. The [`@CFLGS@`](https://gitlab.com/leogx9r/ryzen_smu/-/blob/v0.1.5/Makefile#L42)/[`@VERSION@`](https://gitlab.com/leogx9r/ryzen_smu/-/blob/v0.1.5/Makefile#L43) substrings are supposed to be replaced in the `dkms-install` target, but the target isn't used.
