Please find some comments below (mostly nitpicking).

Codingstyle:

	u8 dir = reg;

Spaces are sometimes nice too:

	if (i2c_read(ADT7460_ADDRESS, dir, 1, &data, 1) == -1)

Again spaces missing:

	if (data == ADT7460_INVALID)

I'll stop here with it. Please fix all this codingstyle issues in this file.

Do you really think this header is necessary? I would prefer to move those 
defines into the C file instead and drop the header completely.

Thanks.
