From: Jean-Philippe Brucker <jean-philippe@xxxxxxxxxx> [ Upstream commit 22d5bd6867364b41576a712755271a7d6161abd6 ] Commit 60d53e2c3b75 ("tracing/probe: Split trace_event related data from trace_probe") removed the trace_[ku]probe structure from the trace_event_call->data pointer. As bpf_get_[ku]probe_info() were forgotten in that change, fix them now. These functions are currently only used by the bpf_task_fd_query() syscall handler to collect information about a perf event.
