Why do you here substitute a "dev->" with "&i2c_dev[adap_no]"? Why not dev = &i2c_dev[adap_no] and you can let the dev-> unchanged.
This eliminates one variable, dev. Another reason is uniformity through the entire driver source.
But it is less readable (at least to me). And it distracts from the reason of the patch, making the driver multibus able. Again, please don't mix Codingstyle, Code optimization and functional changes.
Anyway, keeping that dev won't make any difference other than making the patch a tad shorter...
thanks.
