+ * v4l_experimental/pvrusb2/pvrusb2-hdw.c:
+ (pvr2_hdw_set_ctl_value_internal):
+
+ - Implement a module option that enables an optimization where
+ control changes which don't actually change anything are
+ eliminated. This slightly improves up tuning latency for apps
+ that like to spit out redundant commands during a frequency
+ change. (The change to implement this was almost trivial.)
