Why are you making a separate algorithm driver? This should really only
be done when the algorithm is very generic. This is the exception, not
the rule. These days I tend to move algorithm code back into the only
bus driver that uses them (i2c-algo-sibyte done recently, i2c-algo-sgi
is next on my list.)

As a matter of fact, each time an algorithm depends on specific
hardware, you can be reasonably certain that it should NOT be made a
generic algorithm driver.
