V4L/DVB (7736): This patch adds support for the Micronas DRX3975D/DRX3977D DVB-T demodulator
The module needs an external firmware file.
The module has been tested on a Pinnacle 330e, but with modules that
are currently not part of the linux-dvb tree. So consider this highly
experimental, don't use this code unless you are an experienced kernel
developer.
