Subject: [PATCH 0/3] HID: bpf: some fixes for pre-loading HID-BPF

As I am working on the next functionalities of HID-BPF, I realized that
I had a few issues while preloading the skeleton at boot.

None of the errors are terrible as they are not inducing a kernel crash,
so it's not super urgent IMO.

Regarding the last one, I'm not sure what makes RHEL behave slightly
different than upstream. But I am not sure also that the code matches
upstream everywhere, so lazy loading it seems like a sensible idea.

Furthermore, that also means that the code will not be available until
requested by user space, which fits well in the whole idea of HID-BPF:
if the user doesn't want it, then it shouldn't be it.
