[PATCH] DVB: frontend conversion 

- [DVB] stv0299, tda1004x, ves1820, ves1x93: convert from dvb-i2c to
  kernel-i2c, MODULE_PARM() to module_param(), dvb_delay() to mdelay()

- [DVB] tda1004x: move from home-brewn firmware loading to firmware_class

- [DVB] stv0299: support Cinergy1200, patch by Uli Luckas

This driver needs a copy of the DLL "ttlcdacc.dll" from the Haupauge or Technotrend
windows driver saved as '/usr/lib/hotplug/firmware/tda1004x.bin'.
You can also pass the complete file name with the module parameter 'tda1004x_firmware'.
Currently the DLL from v2.15a of the technotrend driver is supported. Other versions can
be added reasonably painlessly.
Windows driver URL: http://www.technotrend.de/
* This driver needs external firmware. Please use the commands
* "<kerneldir>/Documentation/dvb/get_dvb_firmware tda10045",
* "<kerneldir>/Documentation/dvb/get_dvb_firmware tda10046" to
* download/extract them, and then copy them to /usr/lib/hotplug/firmware.
