This series fixes a number of issues introduced primarily with the conversion to dev_err() and dev_dbg(), which failed to notice that the drivers where using their USB interface and device pointers as disconnected flags (leading to NULL derefs) and that they did not hold references to the structures (leading to use-after-free on release()).
I've already fixed up a few of these USB character device drivers separately, and the uss720 driver has similar bugs that remain to be fixed.
