Subject: bpf: Fix bpf_ringbuf_output() signature to return long
Patch-mainline: v5.9-rc1
Git-commit: e1613b5714ee6c186c9628e9958edf65e9d9cddd
References: bsc#1177028

Due to bpf tree fix merge, bpf_ringbuf_output() signature ended up with int as
a return type, while all other helpers got converted to returning long. So fix
it in bpf-next now.

Fixes: b0659d8a950d ("bpf: Fix definition of bpf_ringbuf_output() helper in UAPI comments")
