[dvblast-devel] [PATCH] Add CA device addressing

[Honza Petrouš]

Add CA device addressing

Some devices has special meaning for /dev/dvb/adapterX/caY
CA device (like fixed TS port input or so). To allow to use
other then /dev/dvb/adapterX/ca0 device there, the command
line option -y or --ca-number were added.
