[ This is a resend (with trimmed CC) of the five Mediatek patches which
  still haven't been picked up from [1]. ]

Driver core holds a reference to the USB interface and its parent USB
device while the interface is bound to a driver and there is no need to
take additional references unless the structures are needed after
disconnect.

Drop redundant device references to reduce cargo culting, make it easier
to spot drivers where an extra reference is needed, and reduce the risk
of memory leaks when drivers fail to release them.

Can someone please pick them up?
