[PATCH] dvb: usb: add supprt for WideView WT-220U
Add support and rewrote some parts with the help of vendor information (Thanks to Steve Chang from WideView, Inc.): o added support for the WT-220U (Pensize DVB-T receiver) o corrected byte order for unc,ber and the pid filter o corrected number of pids that can be fetched at the same time. o added some comments in Kconfig-file o added USB IDs for the WT-220U Signed-off-by: Patrick Boettcher <pb@linuxtv.org> Signed-off-by: Johannes Stezenbach <js@linuxtv.org> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
