Please move kernel doc comments for these members from patch 4/6 here.
Adding new members and comments should go together.

This doesn't compile. Looks like copy-paste from your
dw_i2c_plat_remove() change but here you must access through the i_dev.

You need to convert also the i2c-designware-pcidrv.c.
