Subject: [PATCH] drivers/media/dvb: Use dst_type field instead of type_flags

From: Julia Lawall <julia@...u.dk>

It seems from other code that it is the dst_type field rather than the
type_flags field that contains values of the form DST_TYPE_IS...
The type_flags field contains values of the form DST_TYPE_HAS...

The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@ struct dst_state E; @@

(
*E.type_flags == 
  \( DST_TYPE_IS_SAT\|DST_TYPE_IS_TERR\|DST_TYPE_IS_CABLE\|DST_TYPE_IS_ATSC \)
|
*E.type_flags != 
  \( DST_TYPE_IS_SAT\|DST_TYPE_IS_TERR\|DST_TYPE_IS_CABLE\|DST_TYPE_IS_ATSC \)
)
// </smpl>
