Hmm. This actually causes a new warning even before I start building it:

WARNING: unmet direct dependencies detected for I2C_S3C2410
Depends on [n]: I2C [=y] && HAS_IOMEM [=y] && HAVE_S3C2410_I2C [=n]
Selected by [m]:
- PHY_EXYNOS5250_SATA [=m] && (SOC_EXYNOS5250 || COMPILE_TEST
[=y]) && HAS_IOMEM [=y] && OF [=y]

and the cause seems to be

203b7ee14d3a ("phy: Enable compile testing for some of drivers")

where PHY_EXYNOS5250_SATA now has a

depends on SOC_EXYNOS5250 || COMPILE_TEST
depends on HAS_IOMEM
depends on OF

and then blindly does a

select I2C_S3C2410

without having the dependencies that I2C_S3C2410 has.

How did this ever pass any testing in linux-next without being
noticed, when I noticed within five seconds of pulling it? It
literally warns immediately on "make allmodconfig".

The warnings happen during the build too, as it does the silentconfig.
So I'm not sure how this was missed.

Stephen, does linux-next perhaps miss these config-time warnings?

I have partially reverted that commit in my merge (removing the "||
COMPILE_TEST" for that PHY_EXYNOS5250_SATA entry) because warnings are
not acceptable.
