Hi David,

Looks good. Is there any performance benefit in marking a driver's
struct i2c_algorithm const?

I've applied your patch, I also added a fix to one occurence in the
documentation. I'll push two patches on top of that, one adding const
to all i2c algorithm drivers and one adding const to all i2c bus
drivers (where possible, of course.)

Thanks,
