I do not object to this patch or your patch[1].

However, wouldn't it be better to add depends on I2C at REGMAP_I2C?
When you use REGMAP_I2C, you assume that I2C is already there, don't you?

The previous REGMAP_I2C has not the dependency on I2C.
So, Greert posted following patch[1] to fix it.
[1] https://lkml.org/lkml/2014/8/17/27

Also, if I2C is 'm' (module) and some driver has not dependency on I2C,
build break happen.

Thanks

REGMAP_I2C is meant to be "select"ed by its users. So these users
should depend on I2C, as "select" does not check dependencies.
