V4L/DVB (6316): Change list_for_each+list_entry to list_for_each_entry
The rest of V4L files.
There is one list_for_each+list_entry in cpia_pp.c that
wasn't changed because it expects the loop iterator to remain NULL if
the list is empty.
A bug in vivi is fixed; the 'safe' version needs to be used because the loop
deletes the list entries.
Simplify a second loop in vivi and get rid if an un-used variable in that loop.
