bpf: Convert BPF_DISPATCHER to use static_call() (not ftrace) [ Upstream commit c86df29d11dfba27c0a1f5039cd6fe387fbf4239 ]
Causing the following build warnings / errors with clang-15 allmodconfig on x86_64,

Thanks for the report! This is fixed with upstream commit a679120edfcf ("bpf: Add explicit cast to 'void *' for __BPF_DISPATCHER_UPDATE()"), which was marked as a fix for c86df29d11df.
