Codingstyle:

	u8 dir = reg;

> +	u8 data;
> +
> +	if (i2c_read(ADT7460_ADDRESS,dir,1,&data,1)==-1)

Spaces are sometimes nice too:

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

> +		return -1;
> +
> +	if (data==ADT7460_INVALID)

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.

[U-Boot-Users] [PATCH] I2C Monitor Chip ADT7460 support

[Michal Simek]

Still is there coding style issue.

and you have one extra header file which is uneeded. I recommend you 
move usefull values directly to driver. 

WD: I looked at include/dtt.h there are many driver specific values. IMHO these
value should be usefull move to driver c file. What do you think about?

Michal

You could also run "Lindent" if you don't want to do this coding style 
cleanup manually.

This should be:

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

Again spaces. And more below...

I suggest you run Lindent over this file.
