Hi Lars,

Good catch, especially since those patches might have been merged
through another tree. Completely missed this one.

I think my i2c controllers will work directly with regmap_bulk_read,
so I probably won't need additional changes for regmap. I will rebase
the bmg160 patches on top of the ones that add regmap support.

Thanks,
Irina
