Subject: [PATCH 4/4] mfd: wl1273-core: Remove the header
From: "Dr. David Alan Gilbert" <linux@...blig.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@...blig.org>
