Do we need this wrapper anymore?

Should we also remove twl4030_vibra_data definition?

Why double newline?

I kept the original logic.
It seems that when there's also a "codec" DT entry, the logic is different.

Yes, but that is defined in include/linux/i2c/twl.h. Since I've sent
multiple cleanup patches regarding twl, I thought it would be wise to
wait until the next cycle to remove them all to avoid merge conflicts.
I don't know how I should go with this, since I could:
a) make another commit removing the pdata definition
b) include the pdata definition removal in this commit
c) wait until the next cycle

This is a typo. Should I send v2 or you can modify it while applying?
Thanks,
