* It receives the name of the mezzanine plugged in each slot by SYSFS.
|
||||
No autodetection supported yet, because the mezzanine driver could not be
|
||||
loaded at the time that the tpci200 driver loads.
|
||||
|

* It has a linked list with the tpci200 devices it is managing. Get rid of it
|

and use driver_for_each_device() instead.
