Staging: vt6655 textual cleanup in prep for driver merge

The vt6655 and vt6656 drivers are from a common origin but
have drifted apart with minor textual differences.  There
are two changes:

  s/DEVICE_PRT/DBG_PRT/g

and

  s/byPktTyp/byPktType/g

This significantly reduces the differences between the two file sets
in preparation to merging the common code.  A few whitespace and text bits were
also adjusted.

Staging: meilhaus: convert nested spin_lock_irqsave to spin_lock

If spin_lock_irqsave is called twice in a row with the same second
argument, the interrupt state at the point of the second call overwrites
the value saved by the first call.  Indeed, the second call does not need
to save the interrupt state, so it is changed to a simple spin_lock.
