[PATCH -next] i2c: s3c2410: Remove unused extern declarations

[Yue Haibing]

commit 0d297df03890 ("ARM: s3c: simplify platform code") left behind
s3c_i2c(*)_set_platdata().
commit d78c16ccde96 ("ARM: SAMSUNG: Remove remaining legacy code")
leave s5p_i2c_hdmiphy_set_platdata() declaration.
And commit bad1e6aadd17 ("ARM: SAMSUNG: Cleanup plat-samsung/devs.c and devs.h")
leave s3c_i2c(*)_cfg_gpio() alone.

I don't understand anything from the commit message here.

How about:

"
After some cleanups[*] certain s3c_i2c(*)_cfg_gpio() prototypes
have become unused. Remove them.

[*] 0d297df03890 ("ARM: s3c: simplify platform code")
    d78c16ccde96 ("ARM: SAMSUNG: Remove remaining legacy code")
    bad1e6aadd17 ("ARM: SAMSUNG: Cleanup plat-samsung/devs.c and devs.h")
"

which branch should this go? Samsung or i2c?
