Hi Stefan,
Due to the problem with your emailer, most of the patches failed:
2/15 3/15 4/15 5/15 6/15 7/15 2/15 (the second one 8th in the sequence)
9/15 11/15 12/15 13/15 and 15/15.
In brief, only two patches applied: the 1/15 and a patch also called 2/15
(I suspect it is the 10th patch).
So, after reading our comments, reading README.patches and applying the
Asaulted-patches extension to your thunderbird, please resubmit the patches.

I agree with Devin that the patch 14/15 shouldn't be applied as-is.
I have no idea why zl10353 needs a different setup, but you don't need
to add an extra parameter to identify the bridge driver. There's a field
at struct i2c_client that can be used: i2c_adapter->id.
This is already initialized with I2C_HW_B_TM6000 (although it currently
uses a fake value).
It is still ugly to do some specific initialization like this, but, when
we have no other glue, due to the lack of datasheets, this is a better
alternative than adding an extra fake parameter at the config struct.
All you need is some code like:
