Subject: [PATCH v2 0/3] leds: trigger: legtrig-bpf: Add ledtrig-bpf trigger

This patch set adds a led trigger that interfaces with the bpf
subsystem. It allows for BPF programs to control LED activity using bpf
kfuncs. This functionality is useful in giving users a physical
indication that a BPF program has performed an operation such as
handling a packet or probe point.

V1: https://lore.kernel.org/bpf/cover.1711113657.git.hodges.daniel.scott@gmail.com/
Changes in V2:
- Change kfunc to trigger based on LED name.
- Fix kfunc registration of BPF_PROG_TYPE_UNSPEC.
- Use new kfunc helpers off bpf-next branch.

Daniel Hodges (3):
  leds: trigger: legtrig-bpf: Add ledtrig-bpf trigger
  selftests/bpf: Add selftests for bpf led programs
  leds: trigger: Add documentation for ledtrig-bpf
