[PATCH 4/4] mfd: wl1273-core: Remove the header

linux
2025-06-25T13:33:58Z

From: "Dr. David Alan Gilbert" <linux@treblig.org>

The wl1273 FM radio is on Arnd's unused driver list:
https://lore.kernel.org/lkml/a15bb180-401d-49ad-a212-0c81d613fbc8@app.fastmail.com/

Other patches have removed the core, the ASoC code and the Radio code.
With all those in, remove the header.

Also, tidy the ref in the docs.

Signed-off-by: Dr. David Alan Gilbert <linux@treblig.org>
