please put those registers definitions into the header file and use /**/
style comments instead of //

this is not compliant with the kernel coding style since:
1) the opening '{' belongs on the same line as the switch()
2) the // style comment should be replaced with /* */
3) the body should look like

			if ((ratio >= 0) && (ratio <= K1T)) {
				b = B1T;
				m = M1T;
			} else if (ratio <= K2T) {
				...
			}

please don't start printk's with a newline (\n).

and from the header file:

> +//...................................................

please replace all comments with /* */ style comments.

Once again, let me assure that I don't make those rules to make you go
through some particular hardship ;) 

But if we want to have 'mainline style' then we have to follow those
rules...

Plase just resubmit the patch after incorporating those changes.  From
the actual code itself it seems quite fine to me.
