Hi Jean,

After merging the i2c tree, today's linux-next build (powerpc
ppc64_defconfig) produced warnings like this:

In file included from include/linux/bitops.h:17,
from include/linux/kernel.h:15,
from drivers/i2c/i2c-boardinfo.c:19:
arch/powerpc/include/asm/bitops.h:226: warning: declaration of 'ffs' shadows a built-in function

The x86_64 allmodconfig produces similar:

In file included from include/linux/bitops.h:17,
from include/linux/kernel.h:15,
from next/drivers/i2c/i2c-boardinfo.c:19:
arch/x86/include/asm/bitops.h:395: warning: declaration of 'ffs' shadows a built-in function

Exposed by commit fa4f62e9f3a85490aebe8857e2208c37da851ce3 ("i2c: Build
core and algo drivers with -Wshadow").

Jean, I realise that these warnings are not something your tree has
added, just that you have exposed them. They are a bit annoying,
though. I am using gcc v4.4.3.
