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.
