[PATCH] ARM: s3c64xx: Tidy up handling of regulator GPIO lookups

[Linus Walleij]

From: Charles Keepax <ckeepax@opensource.cirrus.com>

Rather than unconditionally registering the GPIO lookup table only do so
for devices that require it.

Signed-off-by: Charles Keepax <ckeepax@opensource.cirrus.com>
[Fixed up to also handle wm5102 and wm5102 reva]
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

This modified patch from Charles is sitting in one of
my regulator branches.
Krzsystof are you collecting S3C patches?
The MAINATINERS file seems to be lacking an S3C maintainer
currently...

Hi,

This was never sent before to linux-samsung-soc, nor to me. I am
properly listed there:
Krzysztof Kozlowski <krzk@kernel.org> (maintainer:ARM/SAMSUNG EXYNOS
ARM ARCHITECTURES)
linux-samsung-soc@vger.kernel.org (moderated list:ARM/SAMSUNG EXYNOS
ARM ARCHITECTURES)

And yes - I am collecting these (mach-exynos, mach-s3c, mach-s5p and
plat-samsung)

I will pick it up.

Best regards,
Krzysztof
