V4L/DVB (3154): TTUSB DEC driver patch roundup
- Collection of patches from Peter Beutner addressing: - add symbolrates to the DVB-S frontend description - fix capability flags in DVB-S frontend describtion - remove some void casts - disable zig-zag scanning as it makes no sense for DVB-T - set sensible min_delay value - return an error for requested filter types the driver can't handle Signed-off-by: Peter Beutner <p.beutner@gmx.net> Signed-off-by: Alex Woods <linux-dvb@giblets.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@brturbo.com.br>
