I took Arnd's patch instead:
https://patchwork.kernel.org/project/linux-wireless/patch/20210125113654.2408057-1-a...@kernel.org/
But I think we really need the cleanup Arnd proposes during the discussion so
that we have consistent LED handling in wireless drivers. Patches very welcome.
Patch set to Superseded.
