Subject: bpf: remove unused parameter in __bpf_free_used_btfs
X-Git-Tag: v6.11-rc1~163^2~68^2~53^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ab224b9ef7c4eaa752752455ea79bd7022209d5d;p=thirdparty%2Flinux.git

bpf: remove unused parameter in __bpf_free_used_btfs

Fixes a compiler warning. The __bpf_free_used_btfs function
was taking an extra unused struct bpf_prog_aux *aux param
