That's OK.

Here is my reason for supply such hid_transport data structure:
As before, we only have one driver for each transport layer, IOW, the
common driver. In this case, we really need not such transport data
structure. However, there are many driver in one transport layer after
HID bus come, these drivers at the same transport layer implementation
would like share some something each other, these live in common driver
before. If we did not add such transport data structure, we must find
one related driver, and clone it, I think that is not good idea.
In fact, even now, the HID processing logic still do not take care of
which transport layer works under it, the cost just is increasing some
pointer reference operations.

OK, I will post the patch for 2.6.21-rc6-mm1 later. You are recommended
to wait to review that.
My friend yanghong buy a new bluetooth mouse, so I can test bluetooth
nowadays, Thanks him here. :D
Good luck.
