You forgot to add the i2c-list, so I nearly overlooked this patch.
Luckily I haven't, so applied to for-next, thanks! Did you use a script
to find all occurences? Would be nice to know. Also, please take care of
the subject line. "I2c" is misspelled.
@Linus: I am not pushing out today, so if you want to add acks or so...
Thanks,
Wolfram
